It reminds me of a situation I'm now in.  There is a document that
uses metapost to typeset text on top of another metapost image (using
plain tex--I did this project before I started using context).  I'm
using the cmtt10 font so that I can count on some relation between the
length of the text and the space it will require, and I'm handling
line-breaking manually (with perl).

Now the users would like a bolder font.  I don't see a cmttbx10 or
anything.  I know that there is much more to fonts than I now know.  I
hear people talking about virtual fonts and all kinds of stuff.  Maybe
I could get a bolder teletype font by learning more about fonts in
general. 

How could I learn about ways to use other (preferably free) fonts with
TeX in such a way that I'll also be able to apply this new learning to
context, which I'm moving toward more and more?
