I did the Intro to Maintenance class recently, and have since done almost all the things that the Minor Service class lists on my own at Moto Guild. First off I have to say that it's a great place! I have some mechanical knowledge but little experience, and people are very open to answering any small questions I have, or even helping out if something seems off.
They have brake pads and brake fluid for sale if you need any, so no need to bring your own. I'm not sure if they have coolant, but they have distilled water to top yours off, which will get you by until you can replace it if you need to.
How old is your bike? If you think the spark plugs may need to be changed, I would call them to see if they stock the ones you need, or pick them up on your own.
Check your manual for how often the air filter needs to be replaced. If it is time, you probably want to order one from them or bring your own.
I would also try to find the actual service manual online for your bike. It will cover a lot more than the manual and be much more in-depth, plus it will include important things like torque values. It is likely they have the service manual there, whether a real book or on their computer, but it is good for you to have a digital copy as well.
