spring it on me!

I clean and lube my chain every 100-200mi all year long. every 500 or so i take the cassette off and scrub each cog to get rid of the gunk. I also use a dental pick to scrape out around the rear derailler pully cogs. a quick wipe of the front chainrings with a rag doesn't hurt either.

tools:

rag/old t shirt scraps for wiping chain, another "clean" one for wiping excess lube after it soaks on the chain for a while.

cheap dental pick

Park Tool SR-1 Sprocket Remover/Chain Whip for taking the cassette off
Park Tool FR-5 Cassette Lockring Tool " "

i use Prolink gold for lube and Simple Green to scrub the cassette off the bike.

that is most of a tune up. as long as your cables aren't rusty and shifting is good then you don't need to mess with that.

This site is the best I have found anywhere. I also use their tools as they represent some of the best out there. Don't get cheap tools.

Plus bikeforums.net has a great mechanics section with cyclist eager to help

I ride everyday(commuter) and clean/lube the drive train weekly. I also make sure the brake pads are free of crud(especially in winter)and tires inflated(weekly as well). These chores should be done regularly.
FWIW: going from top roping to the sharp end is way more difficult:) Charlie
