Depends. Do you want to get handy with your bike? If so, go for it. It will leave you knowing your ride well and able to deal with the inevitable problems. One caveat: you might not want to tackle all of this in one sitting. Maybe one thing a week? Your call.

If you are never going to want to do a thing on your bike again, take it to the LBS.

BTW, good stuff. I'm jealous.
