Almost all of what you're going to be looking for will be fit in the shoulders. Also be on the lookout for things that are too short or too small. There's a lot that a tailor can do, but when it comes to adding inches to the sleeves or altering the shoulders, there's only so much humanly possible.
This is all correct. Just to elaborate, the length of the jacket and the fit of the shoulder pads are most important. The shoulder pads should cover your entire shoulder without protruding past. When you put your hand from the outside of the arm to up to the shoulder pad, you should feel minimal, if any, padding scrunch up. If you do, try the next size down. Also, the jacket should cover your bum, but shouldn't go more than about an inch past (and most people feel that if should be more or less exact).
Beyond that, you should be trying on multiple suit styles to get an idea of cut. All suits fit some body types better than others; there's no generic "best" suit cut. If you're skinny, a more European suit cut will serve you well (for example, you'll notice a difference trying on the Fitzgerald at Brooks Brothers and then trying a Madison; the former is tapered a considerable amount more). If you're short and stocky or have meat on your bones, American cuts are probably better (that same Fitzgerald will probably look pretty funky on you, while the Madison will fit quite well. Jos. A. Bank is another prototypical American cut. Older lines of Hickey Freeman are also similar, but they've added more modern European lines recently). Finding a suit that tapers correctly is rare, but it's worth looking at because it will look great and save you a LOT on tailoring.
