BTW: welcome to BF. Enjoy the ride.
Lots of good folk here who will give you straight advice. The best you can do with your bike is ride the heck out of it, learn general maintenance, and if you put forth the effort of a lot of google searches and youtube videos, you will get a lot of help here.

Disclaimer: 99% of what I know about cycling I learned on BF. That would make, ummm, 1% experience. And a lot of posts.
