I'd agree with the advice that's already been given.
At this point in your training you don't need to worry about adding in "intensity" methods (or really any advanced training techniques). Sure, if you want to throw one or two in from time to time to experiment with them then, hey, it's your time.
But, take it from those of us who have been where you are and have been doing this resistance training thing for a lot longer than yourself. At this point in your training, really all that you need to focus on is adding weight to the bar (for relatively the same number of reps) and making sure you get enough food and rest to support growth.
Sure, we could probably add in all kinds of fancy terms and big "$20" words and turn training into what would seem like a freakin quantum physics problem to you. But, really at this point you only need to focus on the basics (in fact for just about anyone who isn't an elite level athlete that's really all that you need to do).
Work on adding 200 lbs to your squat, deadlift, and bench. Work on being able to chin with your bodyweight in plates added, work on being able to dip with your bodyweight added, work on being able to do a strict bodyweight military press, work on being able to curl an olympic bar with 45's on either side for reps, and just as importantly eat, eat, and EAT!
When you reach those goals, and provided that you've done your work in the kitchen/at the table, you'll realize that not only were you really overcomplicating things before, but that we vets were just trying to help you to progress the best way that we had found. We weren't trying to keep you from doing some secret technique that would help you build muscle faster.
In summary, focus on the basics. Once you've built a strong foundation, well then it's up to you how you choose to fine tune things.
