I'll try to make it out as well.

Regards core training, check in with Cycletherapy, but I know Velotique has some core strengthening videos for rent. You can find basic routines online to get you started and the book Functional Training for Sports by Michael Boyle is available from the friendly library. It's sports generic but has some decent core strengthening routines and also touches on some less common ones like vacuum's to work the transversus abdominus.
