I presently run CS3 and Lightroom 2.x....forget the exact lightroom update I stopped at. I find Lightroom much easier to edit RAW in than ACR (which comes with CS whatever) and Lightroom organizing system is easier than Adobe Bridge. However, there are certain things that Adobe chooses to hold back from...or can't put in.....Lightroom. Sharpening is much better handled in photoshop, extensive local editing is easier in photoshop....altho LR2 and up does allow some local editting, but I find it a little cumbersome. Color to B&W conversion and control of it is much better in LR....for me, anyhow.
a combination of LR3 and CS2 would be a pretty good combo
