I'm more of a console gamer, so bear with my ignorance here please.
Some of these games are EA through Origin, and with Steam, you can pick a 'delete local files' option, and then re-download that stuff anytime you want. Is that the same with these Origin games, like SWOTOR, Sims 3 and so on? I want to free up space, but I want to make sure I won't have a problem re-downloading them in the future.
Diablo 3 also doesn't seem to have an uninstaller anywhere, and various other games. In those cases, is it alright to just delete the folders directly, knowing that I might lose any saves forever?

Seriously, though, deleting the game's folder should generally be enough. There might be saves or configuration files in some other folder (and some registry entries...) but it shouldn't matter too much.
If you're keeping saves, then I'd Google where that particular game saves its data. --- Could be worse, they could have been American givers and you would have been smothered in small pox. -fakenamefignuts on Indian-Giving. Steam ID: electroflame
I always use Revo Uninstaller, even on programs that have installers/uninstallers. It can uninstall as deep as you want, right down to any registry files there might have been created. It's free too :)
