1. Yeah, that would probably do it.
2. That's from PitBull being upgraded to use the new DogTag-3.0 library. Syntaxes changed and so did some tags themselves. You can go in and change CurMP to just MP or just reset it to one of the default options for the power text.
3. TinyTip is being rewritten by Thrae. I haven't been keeping up on it though. If you're having issues, you can switch back to the stable version of the mod that's on this site, or use a different tooltip addon. I use Cowtip myself, but TipTac is a good one, too (also on this site).
