routine and a question

[R.P. McMurphy]

I've played around with different routines and have found that a push/pull/legs routine works best for me so i've been doing the following for size/strength:

Sunday: Chest, shoulders, and Tris
Bench press - 3 sets of six
incline bench - 3 sets of six
dumbell press - 3 sets at 8, 6, 6
Skull Crushers - 3 sets of 8, 6, 6
abs

Tuesday: back and biceps
Pull downs - 3 sets of six
pull ups - 3 sets at 10, 8, 6
Cable rows - again, 3 sets of 6
preacher curls - 2 sets of 8 and 6

Thursday: Legs
Backsquat - 8, 6, 6
Hamstring curl - 8, 6, 6
calves then abs

I also do cardio before my workouts on sundays and tuesdays. I've more or less tried to stick with heavy compound movements with this one with one or two exceptions. Also, the weight on my reps has been increasing but I'm still bumping it up the same between each set that I have been since I started training (i.e. ten lbs). This means I basically start heavy (for me at least) and end heavy. Should I move to a percentage and spread out the weight more in my sets? Feel free to critique/rip it a new one. Thanks in advance for the replies.

P.S. from what I've seen on this site, it's full of good info so I'm glad to be here

its not bad... i would add deads every other week at least

I agree on adding deads every other week, I would also alternate your skull crushers with push downs every other week. Swap the preacher curls for a better mass builder like basic BB curls or DB curls. And again alternate your DB press with a military press every other week.
Your on the right track with basic compound exercises.

Just asking - why are you doing cardio before your workouts?

[R.P. McMurphy]

I have a very limited schedule with a full time job and being a full time grad student so basically my workout days are the only days that I can do cardio. I just put them before I lift so I don't have more lagtime between when I finish my workout and when I have my PWO shake.

Any more thoughts on bumping up weight between reps? Should I stick with a set number or should I move to percentages?
