This book is a solid intro to programming in a Plan 9 environment.

http://doc.cat-v.org/plan_9/9.intro.pdf

Covers some basic system libraries, how the compilers and linkers
work, touches on using acid for debugging, and a little graphical
stuff.

Besides the man pages and the papers in /sys/doc, the source code
itself is really good.

 I'd say, start by reading the system documentation / papers, the intro
 manpages, and figuring out what you want to work on, and then go from
 there.

 Basically, "just do it," but... figure out what you want to do, then
 what you need to know to do that, then ask specific questions here or in
 the grid or in #cat-v, and experiment and play around :)
