Just adding my .02 about your tripod. I just got a 4x5 myself (Cambo SCX) after being away from large format for more than ten years, and I'm using the Bogen 3036 as well. It is amazingly solid, even when I have the camera all the way to the front of the rail and tilted down. It's like using a studio stand. I don't think it's overkill, I think it's perfect!
