Hi,
There are many videos on the Topaz Labs Blog at http://blog.topazlabs.com/software/bw-effects/ and you may also see many more on YouTube where you can search for "topaz b&W effects" you will see many, many pages of videos.
Unfortunately the User Manual doesn't go into detail about the masking but, in my case, I would typically use the "Overall Strength" slider to tweak the effect (either Dodge, Burn, Detail or Smooth) at the end of my process. Note that it obviously doesn't affect the Color brush as that is governed by opacity.
