Either way I am leaning towards a dedicated set that can in the future fit AP Sprint kit. So for wheels I am looking at Kosei K4R 17x8 +36 or XXR 17x8.25 +35
I am leaning to the XXR because they are cheap and can put a 245 in the future if needed.
Next item is tire itself, if I get a track dedicated set what should I have? If I drive it to and from the track a couple hundred miles what should I have? Which is better option?
Closest track to me is ~150 miles.

It sounds like you're going to end up with a dedicated set of track wheels and tires, and you'll drive to the events on another set of wheels and tires. The rule of thumb with tires is that the tread width be +/- 1" of the wheel width; within that 2" distance, a narrower tire will generally provide you with more responsive handling. If it were me, I'd be looking at 225 tires for either of those wheels - compared to a 245, they'd give you a triple: cheaper, lighter, and a better match of tire/wheel widths.
If you need a 245-width tire due to how much power you have, you might want to consider moving to a 9" wheel. For reference, on a 318 RWHP car weighing 2893# on track, I run 235 DOT-Rs on a 9" wheel. I could run 245s, but they're hardly wider than the 235s and the 235 is already plenty wide for that wheel. And I could, and have, run 255s, but with the DOT-R BFG R1s I run I would need a wider wheel to take full advantage of the 255's tread width.
Once you put the sprint kit on the car, you might consider a DOT-R compound tire. (Mind you, I'm not sure how much experience you have. IIRC, it's just a little?) Assuming you do eventually look at a DOT-R, you could do worse than start with a Nitto NT01. With an 8" wheel, I'd go with the 225, and with a 9" wheel, the 235, or the 245 if you need it.
