Honda TRX300W information and questions… newbie!

Good afternoon!

I recently acquired my first four wheeler. It’s a 1998 TRX300W. It needs some work, and I am having trouble locating the correct parts.

I have noticed that there are many different suffixes when it comes to these wheelers, and I want to make sure I am getting the right parts (which I imagine means identifying the right suffix or model).

I literally cannot find anything on the TRX300 "W". I believe this wheeler is 2 wheel drive with an automatic clutch.

Also, its going to need front and rear brakes, a batt, and some misc tune up parts. I am not familar if OEM or aftermarket is better. Any assistance on where to purchase parts and what brand? Ebay actually seems to have some good prices.

Thanks!
