Do you play live regularly ? Say multiple times / week ? What form of venue ? (Lounge, Club, dinner theater, etc ...) In the larger rooms - does your rig have to fil the house or is there FOH support? Got a roadie and a truck ? (seriously...)
There is the flip side, I've have a the cash, and want the best possible rig in my own listening environment - equally valid usage but without the practicality/transport issue to be dealt with.
There are matters of scale and also practicality to be condidered in giving you a decent assist...
Amplification wise... tough call. I really dig the older Eden WT stuff for 'warm but articulate'. I'm also a big fan of the Avalon U5 in the 'warm and articulate' OR the 'pristine sheen' categories. Given my circumstance, I really can't get behind the Aguillar stuff. I've heard it sound good but ... it is the poster child of impractical for me. It's maybe the oly amp on the planet that makes moving an SVT look like a reasonable option

NOTE: That my rig is first and foremost a stage monitor and that I consider keeping it from conflicting with the FOH a very significant concern. I don't ever want to hear my tone suck on stage but I have a wide range of acceptability given that what is in the FOH in the context of an overall mix and a solo tone is very, very good. Clearly I favor practicality.
If your answer is smaller rooms and FOH support. For commercially available cabs, I would start with the Accugroove Tri-112 and / or Tri 115 cabs.
If your signature is up todate... You aren't going to like what you hear in that MIM Precision for very long ... If you're really into the P bass, part of that 4K might fund a Mike Lull, Lakland Glaub or early 80's Fender with a set of bitchin' cool pickups in it... and you still have room left over for an outstanding rig ...
