Thanks Benz. It's tough to tell exactly where the pops and creaks are coming from but it seems to happen only during hard pedaling and kind of feels like it's coming from the left (non-drive side) crank arm which is attached with hex bolts. The whole crankset has always annoyed me, mostly aethetically with this hi-tech look, but I haven't bothered to tinker with it too much. You're right–the Xtracylce extension could be part of the popping and creaking as well since it's attached pretty close to the crank area. I'll try to do some further investigation especially now that I know a crank replacement will require more than just a swap-out.
