Lots of nice legsets out there, but in the head department, I've been really satisfied with the Gitzo G1570M, low-profile, 3-way pan head. I particularly like it with my 11x14" camera, which is a flatbed design.

I'm using a Bogen 3233 legset, but it will be fine on any Gitzo 3xxx or larger as well as others.

Robert White has good prices on Gitzo.
