This is a really good post because it is something we all need to be careful of. Sounds like your car is in need of some geometry checks. For the tyre to wear on an inside edge would indicate the geometry is out and your throwing awa tyres long before you would have done other wise.
A corner weight and geometry alignment is good money well spend IMHO. I had it done recently and the car drove so much better afterwards and my tyres wearing much better.
If it were me I think I'd have the balancing and geomtry done before changing the tyres. If your going to lay the 911 up for the winter, I'd probably wait until after the winter for the tyre change.
I Think the Michelin PS2 is a good choice. I drive Bridgestone S01 or S02's which are also very good tyres.
