Based on everything in the Office menu in Cardapio:

Ease
Dictionary
Evolution
LibreOffice (and all the related sub-programs e.g. LibreOffice Writer)

Unsurprisingly I use LibreOffice the most as it has everything I absolutely need for school. If I can't use my laptop for whatever reason I use Microsoft Office 2003 or 2007 (whatever the school computer has installed)

LibreOffice Writer, LibreOffice Calc, LibreOffice Draw

[Copper Bezel]

OpenOffice.org Writer and Calc, (strangely not LibreOffice, I know), Softmaker Office Textmaker and Presentation, and Dropbox (not an "office suite" item, but one of the most important packages to my professional life ever.) Occasionally, PDFX-Change Viewer, for embedding comments in .pdfs, and a couple of other weird little .pdf utilities.

Really just emacs with a custom LaTeX-mode, and the latest, stable org-mode.

For my LaTeX set-up, it's basically split between what I call a "normal" LaTeX mode (for writing papers) and a few more custom hacks for writing LaTeX Beamer presentations. This with reftex (http://www.gnu.org/software/auctex/reftex.html) and bibtex (http://www.bibtex.org/) (which both have very nice emacs integration) makes not only navigating easier, but also dealing with tedious bibliographies quite painless.

I do a fair bit of note-taking in courses, and generally find org-mode sufficient, especially it's ability to embed LaTeX equations.

Also, having a personal scheduler with org-mode is very handy, but I probably don't use it to it's full potential.
