my question is what kind of supercharger pulley can you use to boost the new roush blower, if there is one.

Your only pulley change option so far is going to a larger lower pulley which has been done already. I think ATI makes the larger lower pulley/balancer assy. It will most likely require a re-flash/re-tune. Roush is supposedly working on a hp package that includes a upper pulley, but it won't be available until early next year if what I have read is factual. Don't expect a whole lot of hp because of the smallish M90 compressor that Roush usues. I would like to see Roush eventually offer a twin-screw compressor for the 3V Roushcharger like they are for the GT500. The rest of the kit is very nice and deserves a better head unit at least as an option after the warranty period is up.
