Can you confirm wether the exhuast should be emitting smoke at idle? If it isn't, is the idle too lean?
Yeah smoke at idle isn't a big deal. You'd like to see smoke when you punch out of corners, but sometimes it won't be as noticable depending on what fuel you're using. Duneland's advice is pretty good. One more thing to look for is that after a good hard run, the car should come in with a low idle. It's shouldn't sit high before dropping.
