It is true, we need a "programming in ConTeXt" manual. It is
still possible to 'know' how to do things by looking at the way
things are done in ConTeXt itself. For example, in your case
you want something like this:

\def\myCommand[#1]#2{%
 \rawgetparameters[myCommand][param1=defaultvalue1,param2=defaultvalue2,#1]%
 do something with \csname myCommandparam1\endcsname and #2}


This is of course very draft, and can be highly tuned and done
multilingual, but that's much more complex.
