@mjmoody: If there is a was to actually assign what cores are used/for what, then I haven't heard of it (other than MP Assign in Bidule, but that's a PITA that doesn't seem to always work). As far as seeing what cores are being used, just open: Applications > Utilities > Activity Monitor. From the Windows menu select CPU Usage. That'll show you core activity.
As for pops and clicks, you could try Rax like Armegeddon suggested (I'm planning to give Rax as well as VE Pro trials this weekend just to compare for price vs usable features) Have you tried Bidule not in ReWire mode with JackPilot? Like I said, it wasn't intuitive for me to set up Jack, but I've got now. PM me if you need help setting it up.
ALSO, there is a Rax/Bidule feature already built into OSX that I've found works ok as long as you don't use too many VIs. It's called AU Lab. It's in: Macintosh HD > Developer > Applications > Audio. I remember playing with that a couple of years ago. It wasn't enough for what I was I doing, but depending on how stream-lined your live set up is...it's free so why not try it as well? NOT on stage though!
