Font and Typescript Questions

[curiouslearn <curiouslearn@gmail.com>]

Can someone please help me with the following questions so that I can use some
of the typescripts that Wolfgang and some others have so kindly made available.

I will use font Bera as an example, since I would like to use it.

I have a Mac OS X Version 10.5.6

(1) How do I know if I have font Bera? As in, where on my computer do I look to
see if I have font Bera installed?

(2) If I do not have the font, how do I install Bera? I see that there are files
on ctan. Where should I save this?

(3) Once I have installed the font and I have downloaded Wolfgang's
type-bera.tex file, where do I save this file? Can I save it where I save the
third-party modules. Once I save it, do I run the usual texhash, followed by
luatools --generate followed by context --make

(4) Once I have accomplished the top three steps, how do I use it in a document?
Do I just type 

\usetypescript[bera]
\switchtobodyfont[bera,12pt]

OR,
 
do I also have to type \usemodule[type-bera]

I would really appreciate any help.
