I have the same bike with almost 35K - getting ready to do my service as well. Follow the schedule in your owners manual for what to look at. Buy a service manual - you will need it a some point.
Oils - you'll get all kinds of advice on this. I use Mobil 1 V-Twin 20-50 in the motor, BelRay 85w-140 Gear Saver in the Tranny, and Mobil 1 LS 75W-90 Synthetic Gear Lube in the Primary. Very happy with this combo.
Fluids and Oil Filter. O'Rings (2) for the drain plugs, Primary Chain Inspection Cover Gasket (this is where I put the Primary oil in). Don't overfill the oil - 3.5 qts. and check it. Check tires and pressures, belt adjustment, go over nuts and fasteners. I would make sure the steering neck is greased (Lucas Red & Tacky) - fill it until it comes out both ends, and that the is kickstand is greased.
If you don't have prior service records - I like to change spark plugs at 10K, check brake pads, check and consider changing brake and clutch fluids (careful with DOT 4 fluid on paint), and make sure your air filter is clean.
Take your time and know that by doing this yourself, you've saved a lot of money
