Shelby Church and Drupal

I'm in the process of converting our church from Servant Keeper to Shelby. I just got a bare database set up to play with, and it looks pretty slick.

I was wondering if any of you use Shelby and Drupal, and how you make them play well together. We're a small parish, so our needs aren't super-complex, but I'm interested in where you let one pick up from the other; which is the better tool for a given task.

Thanks,
Rebecca
