...I was wondering whats in your library.
My library is the internet.
I would say the first book to read cover to cover is the camera manual. It's probably the most important part. If you don't know what your camera can do or how to do it, then taking good pictures for the conditions you are in is difficult.
F2.8 is just the aperature, you probably won't need to go lower until you start getting really creative. The fastest lens I have is a 50mm F1.8 and that cost me $99 shipped. They get expensive when you get in to IS lenses.
The best thing to do would be to know what the different camera settings do.
Example:
Low F-Stop number = faster shutter speed available and more bokeh in the background
High F-Stop number = slower shutter speed available and perfect focus of background
Low shutter speed = more vibrant colors, light trails, night exposures
High shutter speed = freeze frame action
Low ISO number = less noise, slower shutter speed
High ISO number - more noise, faster shutter speed
Basically, start with your camera manual, take some test shots with different settings and see how they differ

You can take the same shot with these different settings:
ISO 50
F1.8
S-8000
Or
ISO 3200
F36
S-60
The difference is color and noise.
