"Professional" TV Calibration: Is it worth it?

I recently got a new Panasonic viera LED tv listed here:

The salesman tried to sell me on their calibration service, but I didn't get it. I'm mostly happy with the picture, but there are a few shortcomings I've noticed.

When watching sports, any really fast motion seems to lag and not project correctly. For example, watching football games, the ball tends to turn green and blend into the field while going through the air on a pass. I've also noticed the picture tends to lag at times when teams are in no huddle getting up to the line of scrimmage, but as soon as the ball is snapped everything is fine. It's really weird.

I also recently purchased the planet earth series on Blu ray, and I can't help but feel like the picture was better on my roommates tv when the show originally aired on discovery back in 2006 or whenever that was.

The tv has options for vivid color, motion picture settings, A.i. Picture, etc. all which seem to make the picture have more of that soap opera feel, for lack of a better term, to it, which is extremely distracting to me.

All of this has had me thinking about having some one come out and "professionally" calibrate my tv. Has anyone done this yet? If so, who did you use and what was the price range? And I guess what I'm really getting at is, was it worth it?
