TeXShop is a front-end, not a TeX distribution: TeXShop can use any  
TeX distribution for the Mac, and any TeX distribution for the Mac can  
use many front-ends.

Now ---if you mean you installed MacTeX, well, then you have *all*  
TeXLive; that means any package for TeX, LaTeX or ConTeXt which have a  
free public license, like the ones you mention above.

Again, if you mean MacTeX, look into /Library/TeX ---see the  
Documentation and Root folders there. But you'll need days to just  
skim all there is in there.

The ideal way would be to type in Terminal

texdoc <package_name> and press enter

but not all packages have documentation (most do, anyway). The  
infallible way is to put in your document

\usepackage{<package_name>} ---if LaTeX doesn't complain, you have it.

Best,
