I realize now that a lot of you all have never even heard of Van Zandt pickups and what they're all about.
They're a family owned and operated boutique pickup company located in the Dallas, Texas area who make some of the highest quality pickups there are. They mainly gear their pickups towards fender guitars, but their humbuckers work great in Gibsons. They're also pretty pricey.
Anyways Sweetchuck, I have the same guitar as you and the Van Zandt Trubuckers work great in them. I have both of mine coil tapped so they can be split into single coils or humbuckers. They sound great overdriven and can handle pretty large amounts of gain without sounding too flabby or shrill, they're just not really eq'd for heavy metal, which I don't think you plan to play anyways.
I think they may be exactly what you're looking for from what you described, here's the Van Zandt websites description of them:
TruBuckers
True Bucker Vintage:
Built to capture the vintage Les Paul, 335 and other guitars that used the PAF pickups. Vintage sound with just a little more output than the originals.
Lots of top end and bottom. Very attack sensitive.
Good for Rock, Rhtyhtm and BLues, Country, and Rock-a-billy
Trubucker Coil Tap:
Built to allow front and back coil of pickups to be split and used as single coils with switching.This switching allows a variation of sounds from this pickup which goes from a full blown humbucking sound to a split sound single coil sound of a strat or tele. The output and attack is the same as the Trubucker Vintage.
Good for Rock, Rhythym and BLues, Country, and Rock-a-billy.

Sweetchuck keep in mind that your tone is also largely shaped by the amp you play through, in my opinion in many ways it affects your tone even more than the guitar your playing does.
Also keep in mind that good tone is only as good as the person wielding it.
