Motorola Droid :: Prevent Process Startup After Reboot

possible to prevent processes from starting on reboot/boot for Droid 2.1?

there's a few processes that are always running, that turn themselves on, which i infrequently use. a couple examples are Voice Search and Skype, which when I ended processes for, freed up a significant amount of memory and 4 processes. I'd like to be able to set them up something akin to what windows will do, where they are on manual startup, and only start when app is called on. I still want to use the apps, just don't want background processes running constantly.
