A "track" bar is one that locates an axle side to side, not to be confused with a "traction bar" (or axle wrap bar, I suppose). Regardless of the term used, I know what you're talkin' about.
8 psi sounds just fine, but you'll have to determine that on your own. You've probably noticed that you need to run more pressure up front (on and off road) since most of your weight is up front. First, get a traction bar on there then lets go do some testing.
