Congratulations on your purchase. When you get back in, you will need to do several things. Check out Fred T's thread above. For initial maintenance, grease the shock, swing arm, and steering head bearings. From my experience with my 03 200, the rear shock bearings had no grease, the swing arm and steering head bearings had very little grease (but at least they did have grease).
To double your power output, you will need to buy a pipe, remove (or cut out the top of) the air box cover under the seat, and re-jet. The bike will rip when you get it set up right. Right now, it's in the slow motion mode from the factory. It will take less than $200 to make it pull like a 250 MX bike and leave a MX bike on top end.
I recommend the FMF Gnarly woods pipe for tight trail riding and the FMF Gnarly desert pipe for high speed riding. Later on, you may want to change the silencer to an FMF Turbine Core Q, but that can wait.
Just my two cents worth-
