The areas on the clutch where the buttons slide do not look to be grooved out too bad, There is a slight goove but not much. Should I get a new clutch or just have the buttons replaced?

Buttons have changed and don't have a stem,just round with hard plastic side and soft side(fits in the spider) If you can get the clutch off just let the dealer do,if not you will have to obtain the spider tool. Cost of tools not worth buying,may not need them again?? Depends on how long you keep the atv or if you plan on doing your own repairs! OPT

Sounds good. My only other question is how deep can the grooving be, and still be able to just replace the buttons?

If you install new clutch buttons and still has a lot of slack as you twist the clutch back and forth by hand,and still rattles when running,probably won't last. Just a ball park guess,if the groove is 1/8" deep or more on all sides,then could last another year or two?? Depends on how much you use the machine. The buttons are only about 3/16" thick and on a fairly new clutch they will be a snug fit when installed. Only you can make this decision when you've had enough of the noise??? The clutch is 12 years old,nothing lasts forever! OPT

With your clutch missing the two buttons also be sure to check the rollers, and washers next to the rollers. This is the part where the weight rolls up and down on. The buttons you are missing help hold them in place. You should see them on the same parts diagram you saw the buttons on.
