No, BOOST_ROOT is required for Boost.Build, and Boost.Build is quite dependent on the original boost directory structure. So you would need to download a current boost version, and put it somewhere locally (if you want to run the tests). Then BOOST_ROOT can be set to the root directory of that tree.

That's the new name of "bjam". There is a (and bootstrap.bat) in the root directory of the boost tree, which will build "b2".

You don't need the Boost.Build system for that. Just link to the blas/lapack library that you want to use (for example via g++ ... -lblas -llapack -LPATH_TO_LIBS). I just described why there is a Jamroot file.
