Hello Jim,
Hmmm, yeah I have heard of the D2G booting up on its own, haven't really found a solution other than pulling the battery, then again I only read a little bit about this issue. For your second problem I'm not familiar with the D2G setting, but it should be in the "about phone" section.
If you want a better battery meter, I personally use Circle Battery Widget and it works great. Looks real nice on the screen too and it can be customize from colors to the size of the circle.
Hopefully someone will chime in with a solution to your first problem. Most people have problems with their phones restarting...D2G owners seem to be worried about them turning on by themselves and taking over
