Paul,

I'm not sure why you're having a problem with #1. I have successfully checked all child nodes without expanding. I'm using C#, but I wouldn't think that there's a difference in functionality there between C# and VB (I could be wrong).

As far as #2 goes, unfortunately, I think you will have to "walk the tree" to find the checked Nodes. I suggest sub-classing the TreeView control and creating a CheckedNodes collection. Shouldn't be too difficult to implement.
