I need to re-pimp out my mac in terms of programs, firefox add-ons, bookmarks, anything else cool?

Unfortunately, I had to re-clean install leopard after some sort of hard drive fail and I need to start over getting programs, firefox add-ons, cool bookmarks, anything else or other recommendations after a fresh install on a macbook.

I realize that there are probably other posts about this but maybe some fresh insight will be good.

Don’t be sparing either please. The only things I’ve re-got so far are firefox, adium, quicksilver, caffeine, and pandoraboy.

Shareware, freeware, something cool…anything is great!
