Stl is good...  You have to make sure you don't end up making too
many copies of things though.  I guess if you like c++ you know to
use const and & everywhere...  That is the main problem with c++ and
STL, is copying everything all the time.  With careful use of const
and using references instead of copies you can make c++ with STL as
(or about) as efficent as straight C.  Of course, bad usuage of C++
and STL will make much slower much much larger programs.

Autopointers are the way the light and the truth for c++ :)

Wombles!
