Hi 2nd. Ave,
Normally the distributor or dealers will try to sell you as much as possible and they would try to replace all so that they don't have to worry about another item giving way after they had replaced an item.
The Service manager has practically sold you the whole system apart from the compressor and hoses.
How long the present AC last depends on the speed of leakages if any, and the condition of all those components. It could be days, weeks or maybe months.
You have to pay premium prices if done at the franchises or dealerships.
Necessary or not depends on the conditions of all those parts mentioned and how you look at it.
If you want hassle free AC for the next 1 or 2 years, it is necessary. You might want to take some risk by reusing all those components after testing for leaks.
