You must have DPDT switches for S/P or Phase switching. Check out the wiring diagrams at DiMarzio to see how it's done.
For pickups, I suggest a Dual Sound at the bridge, and a PAF at the neck. These are 'classic' pickups. From the way you describe your style, I think the 'modern' pickups like the PAF Pro may provide more harmonic content than you really want.
I have a Yamaha SBG1000 (something like a Les Paul double-cutaway) with a SCHB (DP106, no longer available) pickup at the neck, and a Dual Sound (DP101) four-wire version of the Super Distortion (DP100) at the bridge. For classic sounds, you couldn't ask for more.
I have an identical SBG1000 fitted with a Tone Zone (DP155) at the bridge, and a PAF Pro (DP151) at the neck. It's a lot of fun to play, but it sounds more like Ritchie Sambora than Jimmy Page.
