RKBrumbelow has some good advice for where to put skill points. If you're not having to use Knit Bone too much, you're probably fine not using Mind Jab. If you're getting hurt a lot (especially if you're missing a lot), Mind Jab can be more effective.
The formulas for a lot of the skills can be found in the manual, if you're the number-crunching type. If not, I'd just stick with what feels right.
Also, the futility belt (although hilarious) probably isn't great until you have your legs under you

But, hope you enjoy yourself and feel free to pepper us with questions.
Cheers!
