I have a few comments...
Superprep consists of only 3 preptests... If you are allowing an adequate amount of time each day for LSAT prep, I don't see how you could stretch that into 2 full weeks of prep.
In general, I think that you should try and go through another 30 or so PTs, the PS bibles, and use the remaining 20(ish) PTs to drill yourself on weaknesses. I don't know much about the PS coursebooks, so I can't comment on that.
I cannot stress enough how much it helped me to take 40+ timed practice exams. I was aiming for 175+, and couldn't have accomplished it without taking exam after exam and reviewing them well.
