The easiest way would be to use the updated 'FMCB Nooby Install-Package 2011'.
You can include new apps in different ways.
Either you add ELFs to the install-package (read the FMCB-Tutorials on how-to) and edit the CNF on PC, or you do it later after FMCB is installed (dj's videos should help you).
