Definitely a good setup, altough I'd consider a tripod without a center column. IMO, for the best legs choose Really Right Stuff or Gitzo, for the best heads choose Really Right Stuff, Arca-Swiss, Markins, Acratech, or Kirk. Best clamps/plates are Really Right Stuff, Kirk, or Wimberley.
You might want to look at the Really Right Stuff TVC-23, -24, or -24L (depending on the height you need) and the BH-40 ballhead.
