versatile submersible

[automater]

I know some of you have done somthing simular and would like to hear some suggestions based on your experiance. The idea is to have high AC, saves, UMD, trip/stun, intimidate, and then damage (pretty much in that order). Am I going too many directions or could this work? I dont intend to be a full blown intimitank but would like to have intimidate availible for certain situations. This is what i came up with so far...

As far as feats i would probly eat a cha tome and put force of personality in there.
was wondering if power attack/cleave/great cleave would be worth trading feats for?
Also wondering if sentinal dragon marks were worthwhile?

Dwarf would seem to work just as good if not better or halfling could be fun. what do you think?

thx for any help
