In case anyone isn't aware, Package Control[0] adds an incredibly simple package manager to Sublime in order to automatically install/update plugins. After that's been installed, I'd recommend browsing the popular packages (already linked in another comment) or just hitting Ctrl+Shift+P, "Install", and searching for the names of languages/tools you use.
One plugin I'd recommend for anyone is All Autocomplete. It extends Sublime's autocomplete detection to match across any open file, and not only the current file.
Also Ctrl+Shift+P searches through all of Sublime's and your plugins available actions. Ctrl+P allows you to switch files without your mouse.
