When I first started out, I found YouTube invaluable for picking up hints and tips on baiting, and more importantly rigs.
The number of rigs out there are frightening, and enough to put a novice off... it seems a whole, different language.
My advice to you would be to stick to one, maybe two rigs at most, and keep them simple.
For bottom baits, a simple "blow back" rig will cover all scenarios....

If you fancy fishing pop ups, or a "wafter" (cross between a bottom bait rig and a pop up), then I suggest a simple "D rig" and they don't get much easier than this, utilising a Korda D rig kicker.
Seriously, these are the only rigs you'll need when you're starting out.
