The hardest part of changing the oil on a RC is taking the fairings off. I've always took off both side fairings, it could be done with only taking off the right (throttle side) fairing, but when you drain the oil the from the engine, it may get on the other fairing, but for me it is just in the way to get to the drain plug.
Other then that, drain plug on the left side of the oil pan, oil filter on the front near the starter, oil fill and sight glass on the right.
Air filter is a little more, but once you get the tank lifted it's eight screws (if I remember right), two of which hold the filters in place.
When I need to lift my tank I pull the tail fairing too, just so I don't have to worry about it rubbing on the sides of my tank.
In my experience, none of maintenance on a RC is hard; oil change, air filters, checking the valve lash; but some of it can be a pain to get to i.e. pulling out the air box.
Down load the service manual (its free, http://www.rc51.info/index.php?page=service
) it walks you through most things step by step.
When are you planning/wanting to have your bike serviced? I need to do all that you have listed to mine. I can put together a "how to" or "walk through" together, but it wont be until late Jan. or early Feb.
