Hhmmmm, upgrade to a P3 you say. FWIW I have no personal experience with the deck however I've been reading about TT upgrades for a few years and this is my take. There is quite alot written on the subject both here and on other forums. There have been a plethora of ezine articles on the subject also.
The arm itself benefits from a rewire, Incognito, Cardass, take your pick. The end stub & weight replacement is also very popular and have proven sonic benefits. The P3 has been reported to have speed stability problems, generally on the faster side.
Sub-platter and platter replacement is also popular however the information I have read goes both ways, seems to be very system dependent on what the TT is sitting on. Same comment regarding replacing/upgrading the feet.
Keep researching the subject and don't restrict yourself to one source.
