Also, ditch Khem the minute you get the next non-droid companion. Then ditch him when you get the healer companion. Running Madness spec, with dark charge (tank stance) and the healer guy I'm pretty tough to kill. Was killing gold star mobs 4-5 levels higher than me without much trouble.
Edit: I pull out the healer guy for tougher fights. Usually I have Andronikos out. I hate melee companions. They stand in bad stuff. Also, having to Seethe every couple pulls is pretty normal. Unless I'm using Talos (the healer), I do it every pull even if I'm not hurt much. I just have Seethe keybound to 1 on my numpad, hit it as the last mob is dying and I go straight into it after my last attack animation. While I'm seething, I queue up death field and plop it down when I'm ready to go for the next pack.
