As its the first time you've lifted the tank it pays to be careful.
Fizzer's right, you first undo the front bolts then the rear which is a long pin.
Then lift the rear first, just an inch, to clear the bracket then slide the tank back far enough (about 3") to clear the fairing side pods. Then lift the front about 3-4" while sliding the tank forwards again so that the rear locates back into its bracket. Now slide the pin back in - voila! You now have a tank that is hinged at the back! Still holding the front up, place a 10-12" piece of wood behind the handlebars to under the tank as a strut to support the tank clear of the airbox. Some prefer to hold it up using bungees to the rear grab handle. That bit is whatever suits you. The idea is to have it swung out the way without falling off the bike.
You don't wanna be lifting the tank too far as there are some hoses on the under side that you don't want to disturb too much. You'll get the feel of it pretty quick. When you lower the tank again just be sure to feed those hoses back down with your fingers so they sit back right. Keep an eye on the fuel hose too so it doesn't kink.
Its a ruddy sight easier to do than this all sounds mate!:rockon:
The air box has a few screws around it and is really simple to change out the air filter.
There is also a damn good tutorial with clear pics on how to change plugs somewhere here.
A good guide as to how much play there should be in the chain is to lift it just behind the front peg. It should only just touch the plastic runner on the swing arm. (Put it on the center stand first and spin the wheel a few times to check for stiff links, they will stay bent as they come round - a sure sign of neglect and poss a new chain :spank

Another sign of shagged chain is to shake it up and down at that same point. If it sounds like a baby's rattle then the O rings are gone and its time for a change.
Again there is plenty of help here on the forum for all these jobs and more. Did my sprocket and chain set last week and I'm no genius! Though I did manage to borrow a chain riveter :thumbup:
Hope that gets you started chum!
