I would consider going 2on/1off

i.e. Day 1) Chest & shoulders
2) Back & abs
3) rest...and eat a lot!
4) Legs
5) Arms and abs
6) rest...lots of calories!
7) cycle starts again

The reason I suggest this is because if you do deadlifts on back day (which you absolutely should if you want size) then your back will be fried come leg day if you do not place a rest day between them. Leg day should include squats and your posterior chain (hams, glutes, lower back) need to be fresh if you are going to give your all to squats (which you should if you are serious about gaining size). Further, chest and shoulder day will involve some heavy pressing and you do not want to have fatigued triceps as that may limit your poundages in military presses, bench, dumbell incline press etc..

Do not be afraid of fat :
- bulking up often means putting on some fat along with your muscle
- dietary fat has been shown to increase testosterone levels while low-fat diets have produced reductions in test levels (not good)
- unsaturated fat is very beneficial in a bodybuilding diet.
- eat lots of nuts, peanut butter, avocados, olive oil, salmon to get good fat.
- even saturated fat is fine as long as you do not have too much
- red meat is a great natural source of creatine, and eggs should be a staple in your diet.
-protein before bed to help with muscle/growth and repair.
