For LaTeX, Google the "Not So Short Introduction to LaTeX2E", a fairly short PDF which I found covered almost everything I normally used. There are a million EMACS cheat sheets out there, but honestly I would find someone you know who uses it. Their enthusiasm will probably help you to learn it better. [Personally, I use "vim". :)] Python's own documentation links at "python.org" are pretty good. The language itself is quite simple and where you'll spend most of your time is browsing their library documentation anyway.
