Here's a good overview of firebrick:
http://en.wikipedia.org/wiki/Firebrick
Red bricks also have many different compositions. You shouldn't use a typical building brick for a walkway, it's too soft, and will absorb a great deal of water. This is especially noticeable in the northern climates. Water, whether in steam or ice form, expands quickly, the brick does not.
For that same reason you may not want to use them in a fire. Anyone here camp? Remember the old adage of not using river rocks to build up the firebase? Those too, because of the moisture content, can have failures. Depending on how severe the failure, shards could go flying past you.
For the firebrick in the kettle I'd think you'd want the more dense style of the two. Once they are up to temp they'll hold and radiate heat beautifully. They'll act much like the water pan in the WSM that's filled with sand.
