Greetings and welcome to RIU!
First of all imo using caricature avatar and using jewish slang is hilarious
Now back to topic I'd also suggest check out
www.growweedeasy.com that's where I also got the idea to grow mine. Lot's of articles and information. Couldn't find the thread with mj books but try to get your hands on Jorge Cervantes "Marijuana Horticulture The Indoor-Outdoor Medical Grower Bible" some info may be outdated but still lots of knowledge to obtain, if you haven't got the green thumb yet. And of course lot's of stuff to read in RIU and ask whenever something unknown happens.
8x8 is plenty of room and since it's a bathroom there's gotta be a ventilation outlet right? Makes things a lot easier.
You can start small like with lower wattage hps, they come 150,250,400,600,1000 watts. If no screwups your estimate yield would be 0,5g per watt. The thing is higher the wattage, bigger the ventilation needs are. You have to figure out what your sweet spot would be.
If going with CFL's for flowering you'd better with several actual 42w than one big watt bulb. So you keep em close to the plant at several angles.
Also get a oscillating fan or something similar to give a little breeze to your plants and keep the air moving.
Might be overwhelming at first with so many styles and growing techniques, but actually it's quite easy to start if you remember to K.I.S.S (keep it simple stupid(or stoner)).
PS. Sorry if grammar errors or something like that. English is second language.
