I have Systempanel Lite, as a task manager, another really neat app is Tasker, which lets you automate functions on your phone based on certain criteria.

I have one task that turns off data, and turns on wifi when I am at home, and it turns off wifi and turns on data when I am away from home.. based on GPS location...Its a little complicated to make the "tasks" there are a number of fhow to guides online.
