Jed judging by your lap times at Cadwell I doubt if the shock is holding you back unless you have serious ground clearance problems.
Maybe worth getting it on a dyno and checking the fueling before spending out on the tuning parts.
As suggested maybe more track time would be a better use of the money.
Bit hard to comment on bike as I don't know whats been done to it or seen what its setup is like.
Which is something than can be discussed at Brands on the Saturday evening
