I've written a bunch of VBA code for various things in Excel. I'm looking at migrating to libreOffice. Under Tool->Macros->Organize Macros: the two choices are LibreOffice Basic and Python.
Should I learn one of those, both, or something else. Am I wasting my time altogether? Any suggestions appreciated.
Python is the way to go.

And no, you're not wasting time. You'll look back and say, why didn't I do it sooner.
Python's a great skill to learn - I use it for everything. It's the glue language for virtually every tool out there (you can even use it with .Net).
Documentation for Python + LibreOffice is however a bit sketchy currently, although I don't have much experience with Calc.
There is some work-in-progress documentation at http://documenthacker.wordpress.com (or soon www.documenthacker.com). It has examples for working with Writer, rather than Calc, but you might still find it useful.
