I don't know TNT in detail, but I guess you would have to also download
JAMA (which is available from the TNT webpage), if you need a solver for
1) Am I right that you can use atlas OR tnt?
No, these are complementary. You can use tnt with bindings+atlas, or
with JAMA. You can use uBlas with bindings+atlas.
ATLAS and LAPACK are not exactly the same thing. ATLAS provides a
complete BLAS implementation, but contains only a subset of the routines
provided by LAPACK. I don't know ATLAS in detail, but I don't think that
it has a solver for Eigen vectors included directly (I used
http://www.netlib.org/lapack/lug/node142.html to dispatch the cryptic
Fortran 6 letter names in clapack.h from ATLAS, and they don't seem to
match with a solver for Eigen vectors). So you need LAPACK (Fortran) or
CLAPACK if you need access to a solver for Eigen vectors. The bindings
also work with LAPACK and CLAPACK, so this should be no problem.
The JAMA library (from TNT) on the other hand probably contains a solver
for eigen vectors.
> 2) Should I be using TNT instead of lapack?
I personally prefer uBlas + bindings + lapack, but as I already pointed
out, I don't know TNT in detail.
> 3) do the TNT .h files have to be in a particular location?
I guess the bindings expect them to be in a subfolder tnt relative to
your include path.

Maybe you should have a look at
