Finally Marshmallow is here, now how do I go back to LP?

Yeah, did that.  I've disabled all the apps I can, but you can't disable Weather, News, email, Message+ and a lot of other "system" apps that I don't use. My Kindle doesn't even work, and its running in the background.  I've restricted background data, but it doesn't actually do anything until you check the little box in the menu, and then it puts a snide notification "warning" icon that you can't get rid of.  I have a limited data plan, so I'm always trying to prevent stuff from running.  With my Droid2 I had to run an appkiller just to keep it from crashing.
