Tires
On my F-Body Mustang I run 17x8 in the front and 17x10 in the rear and I run Goodyear Z rated tires. As far as how long your tires will last, it really depends how hard you are on them (fast corners, frequent burn outs, etc.). First of all, you'll want to make sure you get a good alignment when you get your new wheels. A lot of tire places will offer a lifetime alignment deal and its worth it if you want to make your tires as long as possible. Also, since you won't be rotating front to back, you can have them rotated by switching sides and that entails pulling the tires off the rims and putting them on the opposite sides still turning the same direction (which is what I do every few thousand miles or when ever I notice un-even wear start to develop). Its VERY IMPORTANT to make sure you never change the direction your tires turn. As far as changes in steering or handling, if you keep up on your rotations and alignments, keep proper air pressure ( I recommend getting them filled with Nitrogen instead of regular compressed air because Nitrogen is more dense and won't leak or disapate when the climate is really hot) and try to abuse them as little as possible, you won't get any gradual decline in performance.
