Here is a guide and the instructions below:

Removal:

Disconnect negative battery cable. Raise and support vehicle.
Remove lower engine cover. On Celica and Camry, remove right front wheel.
On all models, lower vehicle.
On MR2, remove right hood side panel and cruise control actuator.
Remove right rear wheel. On Celica and Camry, remove alternator from engine and secure out of way. On Camry, remove coolant reservoir tank if it interferes with timing belt removal.
Remove engine control (torque) rod from front of engine.
On all models, remove accessory drive belts.
Using floor jack, slightly raise engine to remove weight from right (timing belt side) engine mount at timing belt cover.
Remove right (timing belt side) engine mount and bracket from front of engine. Remove spark plugs.
Remove Number two timing belt cover and gaskets. See Figure.

Rotate crankshaft clockwise so cylinder number one is at TDC on compression stroke. Cylinder number one is front cylinder at timing belt end of engine.
Ensure timing mark on crankshaft pulley aligns with "0" mark on number one timing belt cover. Ensure hole in camshaft sprocket aligns with alignment mark on camshaft bearing cap. See Figure.

. If hole in camshaft sprocket is not aligned with alignment mark, rotate crankshaft clockwise one full revolution.

CAUTION: If reusing timing belt, mark direction of timing belt rotation on belt. Place mating marks on timing belt at camshaft sprocket and at crankshaft sprocket for reassembly reference. Also place reference mark on timing belt at upper edge of number one timing belt cover. See Figure.

.

Loosen number one idler pulley bolt.
Move No. 1 idler pulley outward, away from timing belt as far as possible. Temporarily re-tighten number one idler pulley bolt. Remove timing belt from camshaft sprocket.
Using pulley holder (SST 09213-54015) or equivalent, hold crankshaft pulley. Remove crankshaft pulley bolt.
Using gear puller, remove crankshaft pulley. Remove number one timing belt cover and gasket. Note direction of timing belt guide installation.
Remove timing belt guide.
Loosen number one idler pulley bolt.
Remove timing belt from crankshaft sprocket. Remove idler pulleys (if necessary).

Revised Timing Belt Tension Spring Procedure (1992-96 Camry):

From Toyota technical service bulletin EG001-99; January 29, 1999: For 1992-96 Camry, the timing belt tension spring procedure was revised. When replacing the timing belt on 1992-96 Camry with 2.2L, tension spring MUST be replaced. The revised tension spring 0 (Part No. 905-7-17003) is a 13-coil design which replaces the original 10-coil design.

Installation:

Install number two idler pulley (if removed). Install and tighten bolt to specification.
Ensure idler pulley is clean and rotates smoothly.
Install number one idler pulley and tension spring (if removed). Pry number one idler pulley away from timing belt area as far as possible. Temporarily tighten number one idler pulley bolt. Ensure idler pulley is clean and rotates smoothly.
Using crankshaft pulley bolt, rotate crankshaft so timing mark on crankshaft sprocket aligns with timing mark on oil pump housing. See Figure.

This will position key-way in crankshaft sprocket at 12 o'clock position.
CAUTION:If reusing timing belt, ensure reference marks on timing belt align with reference marks placed on crankshaft and camshaft sprockets.
Ensure timing belt is installed in original direction of rotation.

Ensure all sprockets and idler pulleys are clean. Install timing belt on crankshaft sprocket, oil pump sprocket, number one idler pulley, and then number two idler pulley in sequence.
Install timing belt guide with cupped side away from crankshaft sprocket and flat side toward timing belt. Install number one timing belt cover and new gasket.
Align crankshaft pulley key groove with key in crankshaft.
Install crankshaft pulley. Install and tighten crankshaft pulley bolt to specification.
Rotate crankshaft clockwise so cylinder number one is at TDC on compression stroke.
Ensure timing mark on crankshaft pulley aligns with "0" mark on number one timing belt cover. If reusing timing belt, ensure reference mark on timing belt aligns with upper edge of number one timing belt cover.
Rotate camshaft, and align hole in camshaft sprocket with alignment mark on camshaft bearing cap.
Install timing belt on camshaft sprocket.
If reusing timing belt, ensure reference mark on timing belt aligns with the reference mark on camshaft sprocket.
Ensure tension exists on timing belt between the crankshaft and camshaft sprockets.
CAUTION: Do not rotate crankshaft counterclockwise, as viewed from timing belt end of engine.

Loosen number one idler pulley bolt half turn. Rotate crankshaft pulley two full revolutions clockwise from TDC to TDC.
Ensure timing mark on crankshaft pulley aligns with "0" mark on number one timing belt cover, and hole in camshaft sprocket aligns with alignment mark on camshaft bearing cap

If timing marks are not aligned, remove timing belt and reinstall.
Rotate crankshaft clockwise 1 and 7/8 revolutions and align crankshaft pulley "0" mark with forty five degree before top dead center (BTDC) mark on number one timing belt cover.
See Figure.

Tighten number one idler pulley bolt to specification
Install number two timing belt cover and gaskets.
Install and tighten spark plugs to specification.
To install remaining components, reverse removal procedure.
Install all bolts/nuts on right (timing belt side) engine mount before tightening to specification.
On Camry, when installing control rod and bracket on strut tower and right (timing belt side engine mount, tighten bolts to specification in sequence.

Please let us know what happens so it will help others.

Yes, you must put on a new timing belt before checking compression.

According to the information I have, this is not an interference engine. There should be no damage to the valves or pistons from a broken belt.

On the crank pulley there is a "V" cut out on the pulley, align to zero on plastic cover. On the top pulley there should be a hole in the pulley spokes, behind the pulley you should see a notch (groove), line that up with the hole, use a mirror to look inside the hole aligning to the notch and put timing belt on careful not to turn pulleys.

You probably did not set the valve timing correctly. Also, your engine is not an interference.

Check if you are getting fuel and spark.

Are the injectors pulsing?

It is possible they are correct. If the water pump seized it could break the belt or if coolant got on the belt, it should be changed.
If the AC compressor siezed it could also break the belt.
Normally shops replace only what is necessary, while it may have been a good idea to rotate the waterpump to see if you hear anything, a bearing should make some noise (waterpump), unless they are saying coolant leaked on the belt.
I would simply ask for a more detailed explanation from the as to what caused the second timing belt failure, a seized water pump or coolant contamination.
Still it sounds like they are trying to work with you. You could also check the local BBB to see if they have any/a lot of consumer complaints.
