First thing's first--STOP AUTOKILLING APPS. You really need to let Android 2.2 manage memory on its own. I raaaaaaaaaaaarely kill apps to start with and it's been documented all over the Internet that with 2.1, task killing was a necessary evil that killed the battery, but with 2.2 you no longer needed an automated task killer because memory was freed up as necessary and actually helps increase battery life FAR better than an automated task killer (which actually made battery life worse).
