Novice seeks Routine Overhaul

Hey all, I have been training for about 1 year and a half now and have made some solid gains, but also lost a lot due to going to college and not eating the same. I have decided I want to take this more seriously and need a complete change of my routine.

Hopefully you all can offer some great suggestions and routines, and not kill/mock my current routine too much. :p Im looking to improve how I work out and my body just like you guys, I just need to start somewhere. Im pretty set on my diet and will tweak that a bit later, but right now my main concern is workout.

Im 18, 5'10
170 lbs about 17% body fat, right now Im looking to bulk and my current routine looks like this

Squats, 3x8
Leg Extensions, 3x8
Ham Curls, 3x8

Tuesday:
Flat Bench, 3x8

While you have an Open mind, run away from the typical western periodization split as far as possible. Start going through the Workout forum, there have been a few training theories posted and read up in the PLing forum.
