Hi and thanks for using 2CarPros.com.
It sounds like you have your hands full. However, it does have a lot of miles. As far as the shaking, often times tire balance will cause what you described. The tires hit a speed when they shake and then work through the vibration as you increase speed. Check to make sure the tires are in good condition, too. Check tread, check for separated belts (bulge or out of round) and also check all steering components.
The wiper issue seems to be switch related. I have attached a flow chart to guide you through checking it. Here are the specs and pin information:
Measure the resistance value at terminal numbers 27 and 28. The resistance value should rise smoothly from approximately less than 2 ohms ("FAST" position) to approximately 1 ohm ("SLOW" position).
As far as the stalling, strange smell. I need to know if the check engine light has come on, if you can describe the smell (is it a sweet smell, rotten egg?). Also, if the check engine light is on, you need to scan the computer to identify trouble codes. They will lead us to the issue. Here is a video which shows how to scan the computer. If you do not have access to a scanner, most parts stores will scan it for free.

Let me know what you find or if you have other questions.
Take care,
