A very simple solution is just to use site.html and print the content
of the various variables and try them out there. A streamfilter is
very much an extention of the rendering context with the req and data
(that gets expanded as local variables for rendering). Once upon a
time I needed this (when migrating to Genshi), and I published a
simple site.html example of the things I poked into to understand what
is available when rendering (+ a useful template for making test calls
of functions and acting on data):
http://trac.edgewall.org/wiki/TracDev/PortingFromClearSilverToGenshi#Debugging
The site.html is a simple way to get lots of information quickly - and
hopefully it still works :-)
There is also a developer plugin with various features (including
details of variables). It may also be worth looking into if you want
to understand more of the internals for plugin development:

PS! For your actual href question, you want to read the source of
trac.web.href.Href class, IIRC it is well documented with doctest
showing how to use this link-creating utility class.
>>> from trac.web.href import Href
>>> href = Href('/projects')
>>> print href.testing('one', two='myarg')
/projects/testing/one?two=myarg
Trac adds such a href (relative path to the current project) and a
abs_href (for absolute urls) to req (aka Request object) with correct
base paths - ready for your use. BTW. Searching the Trac source code
for patterns is still the best way of getting usage examples...
