[OS X TeX] available fonts & how to invoke?

[Murray Eisenberg]

Can somebody give me a pointer to a _contemporary_, more-or-less 
comprehensive listing of what text + math font sets are available and 
what the corresponding command is to invoke each set (for the entire 
document).

As to invoking the fonts, I mean things like:

\usepackage{lmodern}
\usepackage[T1]{fontenc}

What I find on-line is horribly fragmented, often focuses upon the fonts 
themselves or how to install them, is somewhat out-of-date, and omits 
the user-oriented simple question as to how to invoke the fonts.

A more specific question: does the invocation shown above for lmodern 
automatically use the (still beta, I believe) Latin Modern _Math_ fonts? 
If not, what additional command is needed?
