Why do these keep popping up?

[King Stampede]

I have Advanced Task Killer Free and it always shows Voice Search and AT&T Navigator keep coming on after I kill those apps. Can I disable them from running? I don't believe I have any apps running that require for those 2 to be running. Excuse my naiveness. This is my first Android phone and I'm still learning. Also, I've had my phone charging for about 45 minutes and the charge only went up 2% since. I turned off wifi, syncing, and whatever else should be draining the battery. Any suggestions on what I could do to have a longer lasting battery?

voice search is ok, the reason AT&T nav keeps popping up is because it's AT&T's bloatware. You'll have to root and download Titanium backup to remove the AT&T aps.

Battery tends to charge slow for me as well as other people.
