The essence is that you keep a simple rule of having GreenBarCycle
short, and in order to keep it do whatever available to you. Good
and suitable solution will emerge by itself or you'll get smart
enough to discover it.

For some hints:

To TDD database, go for the model first. Don't consider it's saved
on the disk. Consider it in-memory database or something. As soon
as you touch the persistence layer, which must be somewhat later,
you can use mock objects(google it).

I don't know what you mean by Form exactly, but guessing from my
experience that most XP beginners suffer from TDDing UI jobs, I'd
give you the following hints:

Make the presentation layer thiner and thiner. Have a look at MVP;
it is much easier to TDD than MVC.

If you try these ways, your design will improve enourmously as a Throw-in.
