There is enough material on this site to give a bookworm a raging hard-on. You've hit the goldmine of weight training.
Now: look up stuff from Charles Poliquin, Dave Tate (this guy knows strength like a hooker knows sex), Don Alessi, Charles Staley, Chad Waterbury, and Ian King. Guys, fill in the rest that I missed.
Lurking around will be a big help too. Threads spring up here on every topic such as hypertrophy, rapid strength gain, mass gain, nutrition, supplements, etc. Read them all. The archives will ultimately answer every question ever conceived if you take enough time to scour them through and through. Ive done all that, and it's paid off over and over and over for me.
These guys here will point you to powerlifting sites, Oly lifting sites, nutrition sites, on and on. The nutrition guys like Berardi and Lowerie and Barr write articles and dish out advice on power nutrition, eating for mass, eating for fat loss, eating for hormones, eating just to eat, on and on.
