Agree with Lloydc that the weak point of any lower-end Rega is the arm wiring and counterweight. Absolutely concur that you should do them first.
OTOH I don't think that footers or running the motor from an iso transformer are invariably a waste of money. If your TT is not on a stable base, especially a wall shelf, or if your electrical supply is poor quality, they may be useful.
I think that Lloydc is quite right, though, in pointing to a turntable upgrade as the most desirable way to spend money after the arm.
