I think the P pickup placement in a straight P vs. most modern (certainly Fender) P/J's is the same, so for the most part, if you get a PJ, you can still have a straight P as well, just by turning down the J pup..
Regarding the roadworn Precision (I have one, Fender not Limelight), what you get with those is a Bass that somehow feels 'played in', I've recently given mine a bit of TLC, by adding a tug bar and a bridge ashtray, along with a set of TI flatwounds, and at the moment I can't put the thing down.
I know there are other Roadworn owners, Marc S for one, who'll be along to sing the praises too.
Hope this helps!
