Okay, I'll post the build I wound up using. Went with healing amp over DPS (Human over Half-Orc, in other words).
Can't find a good character planner to export, so this is going to be a bit of a mess.
Side note, tomes are completely unnecessary for this build, though they do help. In addition, while I don't max str/con (take con to 16, put a few into int and rest into cha), if skill points aren't important to you, you can. Could do something to the effect of 18/8/18/12/8/8 even.

As a side-note, I do find it a little amusing that my thread over a question that took me over a month to decide gets necroed (and posted in for the first time) after I get back to level 20 with my decision. :P
So far this build is working quite well, and I can't wait to see how it performs with full twists (though that'll be a bit from now, as I don't have that much sanity to spare at this time of year).
Edit: Currently planning to be lazy with twists and only get 1/1/1 instead of 4/2/1 capabilities, as I'm currently planning to get Brace for Impact/Primal Scream/Rejuvenation Cocoon. Eventually will get Sense Weakness available...but too much work for now. :P
