The main consderation on the rims is the
width, not the diameter. More HP = more width. For 350rwhp, you'll need at least 275s. For 550rwhp you'll need at least 315s. Anything above 700rwhp you'll need at least 335s.
To fit 315s you'll need to trim (not roll) your rear inner fender lips. Rolling enough to get the clearance you need will distort (bend) the fender. Trimming is quite easy with a reciprocating saw. Trim, grind smooth, paint. It only takes about 30 minutes a side, and results are 1) perfect, and 2) no downside whatsoever - the fender retains all of its strength.
The stock exhaust will handle about 500rwhp with no problem. In my experience, if you're doing exhaust as one of your first upgrades, it's mainly for looks and sound...not performance.
The need for brake and suspension upgrades depends on your application. If you can swap in TT brakes, it'll be more than you'll ever need for daily driving (even 'spirited') daily driving. If you're planning on roadracing, you'll want to look into suspension upgrades. If you let us know more about exactly what you want to do with your Supra, we can provide you with more specific advice.
