You get new stuff on missions, can buy them at stores, or obtain them via downloadable content.



For all the armor parts available standard in the game, take a look at the overview at the bottom of this page:

You can't buy stuff like ME1. You acquire weapons during missions and can purchase accuracy and damage upgrades for weapons, and purchase damage resistance, shield, and health upgrades for armor. Disappointing because there's less of an option, but somewhat better because it's simpler.
