1. It's all stub, so I'm sure that will be in. I saw a high-res shot of an item and you could see how many AP it took to use that.
2. That may not be in yet either, but since they say it's in, it will be in. Preferably with a distance per AP indicator. Technically, I don't remember seeing Scarlett's stats.
3. You can go anywhere on one of the four large Divinity 1-sized maps, including houses and dungeons. You can't cross from one huge map to another without both part members being together, though. You might be able to advance some main plot things, although how that will work is uncertain. Larian has mentioned that you can kill everyone and still advance the main plot.
