If you're just getting into tracking for the first time, I would just go out on the Arc-8's and PSS's for an event or two and see if you get some clarity. You might find you're satisfied with the performance and don't want the hassle of a second set (you'd have to change them at the track if they're R comps). I have been tracking on my stock 261's with 235f 255r for a few years now and am happy enough with the performance and cost savings to not get a second set. After all, the best mod is the guy behind the wheel. Get some experience first and then see if you want to make changes.
