Other then studying, practicising and possibly contributing I'd start following some of the employees on Twitter. You can find some of them on hacks.mozilla.org/ - people like twitter.com/linclark
Befriend them if you can, because I'm sure they'd be thrilled to give you tips seeing your enthusiasm!
Do only certain offices work on the projects I want to do?

Don't know unfortunately, maybe check on careers.mozilla.org
BTW have you thought about doing an internship there? careers.mozilla.org/university/
Be yourself :)
I hadn't thought about following some employees, that might help if I can get some mentoring from them :) Thanks!
