Jaime Rodriguez (http://blogs.msdn.com/jaimer/) have just posted the materials from the WPF for Line of Business Tour. Download the decks and demos from the cookingwithxaml.com site (Deck, Demos)
For anything WPF, make sure you subscribe to Jaime’s blog, he’s got a running list of WPF Discussions (FAQs) that will surely help address most of the WPF queries you have in mind.
And while at it, check out Karl Shifflett’s blog on WPF too (http://karlshifflett.wordpress.com). You may download his MVVM training day resources at (http://karlshifflett.wordpress.com/table-of-contents/education-day-creating-wpf-line-of-business-applications-m-v-vm-using-c-and-vbnet/)
