I am not an expert by any means for IMS, but I recall earlier models were double row, what makes them less prone to failures.

Shocks - for sure, if never replaced, will "need to be done", meaning you will be fairly OK, but the ride quality is impacted.

I personally am getting rid of 19's from my recently acquired car. Not only they rub, but also they make the ride very harsh. Maybe it will be OK for you. If stock wheels are available - take them.
Sport exhaust? Mine has "Pedro mod" and it is not for me, but that is personal.

Hard to advice - mine looked nice on pictures, but in person was not so good anymore. There were many tiny things - foam in the vents (typical), microswitches in windows (typical as well), faded paint here and there (black car in Florida - typical)...
