I don't use a lensbaby and don't have any great resources for you, but seeing that the question has gone unanswered for so long, I'll post what I can...
Craig of The Mindful Eye uses a Lensbaby. Back in the day he posted more how-to stuff about using it, but there are some of his photos along with nuggets of info in his blog:

...he also seems to be good at answering questions, so maybe you can ask him directly? Or search his site and see if you can find more useful information -I stopped following him after he changed from his old site to this new one, so it's possible that I missed some better resources there.
