Than is there a way to stop apps from launching in the startup process? Like Sprint navigation which I don't use. Or like mp3 store which I don't use.
You can root your phone and install the custom ROM in the hacks section. Otherwise, no there is not way to manage these apps.
not entirely true, TasKiller will kill sprint nav ect. But wont keep it from booting at start.
Why no task killer?
There's a "startup cleaner" app. Not sure if this will stop them from launching in the beginning. Haven't used it yet..
Startup Cleaner 2.0 - Android app on AppBrain

dont know why everyone is so scared of them
Why no task killer?
It's recommended NOT to use one unless you know what you're actually killing. Lots of people just download the app, set up one of the presets and they cry that their alarm clocks don't go off.
I've used a task killer since launch with no issues, but I kill apps manually and know exactly what I'm doing and it works well for me. Can I tell a difference between having 100mb of memory and 200+? Yep.
