If you want something roughly eye level and 3 sections, get the GT3530LSV (ignore the video bowl, you don't have to use it). If you want the capability to shoot higher off the ground with four sections, get the GT3540XLS.
For a ballhead, get either the RRS BH-55, Arca Swiss B1, or Markins M20.
Any of the above combo's would be very sturdy, reasonable weight, and very user friendly - though not cheap.
