I will soon be a proud owner of a Reef Angel, and Its time to start looking at the code

I have almost no experience with code, except for html.
I see alot of the guys here are really clued-up in coding, at least I'll have some pros helping!
The unit I am getting is :
Reef Angel Head Unit
2 x Relay Boxes
3 x Temperature Probes
Ph Probe
Relay Expansion Module
Salinity Expansion Module + Probe
RF Expansion Module
Wifi Expansion Module
Expansion Hub
I see that there is already developed libraries available , does anyone else have the same setup that did some cool additional things on it?
I think I'll have loads of questions, be patient if you don't mind.. Im a total Noob with this !!!
