congrats on the bike. IMO you have a great bike. Later model "improvements" are not really that great. Linked and assisted brakes you can do without, the change in steering geometry supposed to improve low speed handling seems to make the bike more sensitive to wheel imbalance and more prone to headshake.... I wouldn't trade my 2000 for a newer one.
What to do? Keep it simple, BMW specifies a BMW "Inspection" every 12K miles. Since the bike is new to you and you don't know the serice history, I'd just do everything on that list.
Going from memory that includes crankcase, tranny, and final drive oil changes.
Air, fuel, oil filter, sparkplug changes.
Valve check and adjustment if needed.
Brakes are supposed to be flushed annually as is the coolant.
Because lots of fairing parts need to be removed (referred to as Tupperware around here) and the gas tank needs to be removed you'll want to do the air and fuel filters, and valve check at the same time. Coolant change is also easier with the gas tank off.
I got a BMW service manual before the Clymers aftermarket became available. By most accounts the Clymers is quite good.
I get my service stuff from BeemerBone yard or local BMW dealer.
The boneyard has the Clymer's manual too.
I use all stock stuff, I'll let other argue the merits of other, better or cheaper air and oil filters (splitting hairs and not worth the trouble IMO).
Lots of data going back years on this site. You do have to sort the wheat from the chaff so to speak though.

I have no service records so I'm going to treat it like nothings been done for a while. I changed the rear oil (a little dirty, no metal on the magnet), I'm changing the spark plugs, engine oil and tranny oil this weekend.
If this was your bike what work would you do next? I'm really excited and thanks in advance for any input.
