Old Settings

I'm moving to portable apps.. I like the idea of having Firefox, Sunbird etc on my stick... However, I already have all the programs set up on my hard drive and I have their settings tweaked and such to just the way I want them. Does anyone know how I can copy these settings over to the portable version so I don't have to do them manually. The biggest help would be transferring my sunbird calendar b/c I do not relish the thought of having to manually enter all of my dates and tasks again

Thanks.
