I agree that upgrading the phonostage and cartridge probably makes the most sense with your budget. I'd probably recommend a modified EAR834P for about $2K. That will leave you with $1K for a cartridge. The Rega P3 is nice player and you should notice the improvements. If you want to take your table to the next level I'd recommend getting out of the Rega line and trying something like a Nottingham.
