The choice for math fonts is somewhat limited, because so few fonts have 
the necessary symbols and spacing information, even if they are 
reasonably complete Unicode-wise.

You basically have three supported choices, and one experimental choice, 
set with the mathtext.fontset parameter:

    cm: The TeX Computer Modern fonts
    stix: A new math font designed to blend with Times
    stixsans: A sans-serif math font (similar, but not identical to 
either Helvetica or Arial)

    custom: Provide a Unicode font -- this generally doesn't work very well.

As for your second question, it should have worked to set all 
non-mathtext text to Helvetica.  Do you have any other customizations in 
your matplotlibrc file?

Cheers,
Mike
