What resources have you used for home learning to pass the 70-573 exam. There does not seem to be a book released yet to cover the exam.
Personally, I did the 3 week Certified Master training in Redmond. After that the 70-573 exam wasn't too difficult. Failing that, I recommend Becky Bertram's study guide (contains links to the relevant sections in MSDN, the Ignite training videos (if you can find them - I think Paul Andrew's blog links to them), and some good books such as Sahil Malik's Building Solutions for SharePoint 2010.
Make sure to get some hands-on, for example work through the labs.
Critical Path has created a series of videos on YouTube which contain exam prep for both 70-573 and 70-576
In addition to Becky Bertram's blog post which has already been mentioned, I would suggest Wes Hackett's post. Both are linked below.
I don't think there is a one stop shop for the exam, even when a exam study guide based book comes out. All the book can do is cover the subject matter, if you aren't confident in one of the areas you need to explore it further with other resources (web, books, training etc)
