Before we can answer your questions, answer these:
What kind of riding do you plan on and what do you want out of the tires as a priority? Your new bike wears common sportbike tires, so the spectrum is from full-race gummies to sport-touring tires.
Does the bike have the stock exhaust? Has it had the jetting altered? If the exhaust is stock and you plan on leaving it that way, jetting should be acceptable. It can be improved by shimming the needle and drilling out the mixture screw plugs and giving them a little tweak. If it has an aftermarket can and hasn't been rejetted, you should rejet it with a Holeshot, Ivan's or Factory-Pro kit. If you want to loose the airbox, plan on a Holeshot or Factory-Pro kit and some PAIR block-off plates. Obviously, if you plan on exhaust mods, plan on a jet kit, too.
Does it consume oil? (This is about the only known problem with some 2001 and early 2002 models - see the 1200 FAQ's for more info.)
