Here's what I do...
I top the tank off and add some Sta-bil. It's good to run the bike after adding the fuel stabilizer to make sure you get some into the carbs (some fuel will sit in there, too).
Change the oil (I assume your shop did this as you mentioned). I've read that's the last thing you should do before saying good-bye for the winter because the used oil can actually create an acid that will corrode engine parts after sitting for awhile. When you take the bike out again in the Spring -- change the oil again.
Here's another one -- I take and put an oily rag in the tail pipe to keep any condensation out of the exhaust (if you store your bike in a shed like I do). Don't want the water rusting out exhaust parts.
Don't forget to yank the battery and keep it charged. I use a battery tender and have had no problems. My buddies just go out and start their bikes up every couple of weeks.
I've also heard you should elevate both wheels but I only have a rear stand. I haven't had any tire problems so far.
Other than that, I just cover it and cry until Spring comes....
