It's not completely clear to me what you want to do.  The best free
font analyzing tool I'm aware of is ttx (see fonttools.sf.net) which
can handle SFNT-based font formats (including disassembling of
TrueType and CFF formats).  Type 1 fonts can easily be disassembled
with t1disasm.

Currently, there is no interface in FreeType for getting hint data,
and I doubt that it is a good idea to expose this data at all -- it is
simply far too low-level and subject to change if necessary.
