If seen all these issues with the 1998 V70's, so it's not uncommon, especially with the mileage you have on your car. I have a few questions though:
What is wrong with the charcoal canister? Was the check engine light on?
Which mount is bad?
Is there any noise from the sway bar bushings?
What is wrong with the A/C?
Have you considered taking it to an independent shop? Our directory shows one in your area, and they have a good review from one of our users:

Make sure you ask the service advisor how severe the problems are. Have them rate them from 1-5, 5 needing replacement now. Some shops are more proactive and recommend parts when they are showing signs of wear, but they are not urgently needed. You have to consider the 120,000 mile service that is coming up soon, it is quite expensive!
Find a good independent shop and you will save $$
