Bulk Phase Training

I am entering a bulk phase and was wondering how I should adjust my workouts as far as # of reps, # of sets, types of exercises, amount of time spent in gym, # of days per week, etc… I have adjusted my diet accordingly but being as how this is the first time I have whole-heartedly decided to commit to bulking up, I am not sure how I should adjust my time in the gym. Also, how much time is good to spend in a bulk phase, and how much time will I need to get back to my summer build. I know it will have a lot to do with my cardio and diet, but should 6-8 weeks of cutting down get me ready for spring break?
