What is the best web design program to create CMSB sites?

We also use Dreamweaver to manage our site design files. For the most part it works very well with CMSB as the backend system. However, once built, I often find it easier to work with Firebug in a web browser for doing the CSS development and then just copy these changes.

Talking about design tools is a difficult thing though. For some, design begins and ends in Photoshop/Illustrator/Fireworks/The Gimp. Most time spent on "web design" these days is really some form of markup rather than graphic arts. With the advent of improved CSS functions, many things that we used to rely on Photoshop for are now coming into the markup work - which means we can easily use a basic text editor or Firebug.

You will still need some form of graphics package for most projects, but the parts made from there are generally assembled in a text environment. Dreamweaver does a reasonable job of this most of the time, and can really simplify your life if you have dozens of sites to manage for clients. However, if the number of sites is fairly low, you might do well with something like CoffeeCup's HTML editor or even just a text editor and your web browser.
