Alright mate, like Mackers has said you need more high reps' if you don't want too much size. 15 reps' is what I'd go for if I was you. Although I would do 10 - 12 reps at first to bulk and then higher the reps' to maintain a size you are happy with.
You could do it like this.
Monday: Chest and Back.
Tuesday: Cardio.
Wednesday: Shoulders and arms.
Thursday: Cardio.
Friday: Legs.
Saturday: Cardio.
Sunday: Rest.
Or if you don't wish to train so often, do the cardio after your weight sessions.
When doing the weights you need good control. I like to come down slow and power it up, but with control. Basically, you need to use your muscle to push and pull the weight, not momentum. If I do my back, when I pull the weight down if I can't hold it there, then I never used the muscle to pull it there. I don't hold it there, but I use that as a good indication. Does that make sense?
I like 20 sets for major bodyparts, and 12 for the smaller ones like Bicep and Tricep. Some prefer less, but I find it works for me. Remember to warm up, and include these as part of your full workout. You could do 4 warm up sets and 12 heavy sets.

You'd be better putting these into youtube, and putting 4 together for when you go the gym and then doing these. Remember, I'm no expert myself. So before your back day, you tube them.
