NOLA,
I installed the stage .75 (fronts and sub). Based on your description definately go with the JL- Stealth for the bigger hit on the lowe end. I would recommend not skimpig on the amp for it. The Rainbows will give you the clarity you want. Even going with only the front soundastage I was very pleased with the clarity and the depth they added. With an eclectica taste like mine I was really pleased, (everything from NIN to Tim McGraw and a little Beethoven thrown in. The dynamics are all there. I'm not as picky about the fill but you would likely want to go with the full Stage 1 for a little more clarity in the back.
BEst Regards,
