Only things I don't use. Disabled GTalk, Music, DSP, and a few others that start at boot and always run. I use PowerAmp, which unloads when not in use. Other minor apps I shut down when I finish using them (games, browser, etc.), but not the important ones. Also, check sync schedules. Some things just don't need to check in every 5 minutes.
I also use JuiceDefender Ultimate, which makes a big difference.
