On your Deadlift I'll send you to this youtube video. Compare her form to yours. I am not a trainer, but I think you could use some improvement in form (couldn't we all?)
On your Squat I believe you are rounding your back at the bottom, I would be surprised to learn I don't, but that dosen't mean we can't do it better. There is a thread here dedicated to squatting correctly.

Other thoughts:
Creatine: You might have put on weight, but the intake of creatine won't increase your bodyfat. It may cause you to retain water. It should allow you to work a little harder after you have taken it awhile (I am far from an expert here).
Body Fat: How did you get that checked?
Diet: This is pretty much the key right there...So what DO you eat over the course of a day?
Welcome to the Forum as well. It's a good bunch of guys here.
I live in PG at that time as well. I moved to Calgary in 2001.
