<p>My boss thinks the VS 2008 IDE Window Manager(autohiding, docking of Solution Explorer, Properties, etc) is the best thing since sliced bread.  I can't find a control that resembles that functionality in the Toolbox.  Is there a control like that available that you know of?  Or should I go ahead and implement it myself?  Btw, we're using VS 2008 Express.</p>

You should check out
SandDock
. The older versions were freely licenced (dunno if they are still available) and the newer versions are relatively cheap, especially considering the amount of time/money/sanity they would save you.
I would strongly recommend against trying to roll your own VM component. There is just too much work involved, and it wouldn't be worth it, if it wasn't your primary product.
