Check out the book Dinosaur Training by Brooks Kubrik. Good read, and it is along the avenue of your goals.
As far as how many days you train, that is up to you and your comfort level. I'd say 3-5 days, keeping mostly with the big compound lifts, low reps and high sets.
If it helps you, here is what I am doing now. I am getting stronger by the week it seems. Maybe this is due to the fact that this is my first time training with this low of reps, but whatever it is, I have found a solid program that works for me..
Deadlifts- 8 sets, starting with triples, working my way up to a set or two of singles.
DB Bench supersetted with DB rows- 5x5, although the last two sets I may up the weight and go to 3 reps.
3-5 sets of finish work for chest and back, higher reps, for the pump, or some core work
Bottom Position Squats- 8 sets, same as day one
Superset 5 sets each of dips and pullups.
3-5 sets of core, grip or arms
Power cleans, 8 sets same as above.
Military press supersetted with pulldowns (different grip than pullups) 5 sets each, 5-3 reps
3-5 sets, rotator cuff, neck, core
Sometimes, I'll combine cleans and presses into the clean and press for eight sets, and include good mornings.
I lift 3-5 times weekly, depending on my schedule and energy levels.
