Well, perception would help you. Perception gives mct (melee combat tacitcs) which will let you roll higher. Also + mct clothes (such as the +9 mct pants) and + perception clothes will help you roll better.
As a low lvl I would use Consistant Technique and Detect Vulnerability for sure. You can also use Empty Mind and Precise Blow or Engergized Attacks (if you run the last two you can't get a enemy dazed/staggered/off-balanced which you need for some abilities that you'll get later).
