Hi Bryan
I'm not a huge Parallels expert, but this might point you in the right direction.
One of the Virtual Machine configuration options under Optimizations is "Tune Windows for speed". I believe that amongst other things, this removes the start animation on Windows. So if you have this ticked, it'll probably account for the Windows Logo being missing.
When you install bootcamp, you activate Windows. Then when you boot your Bootcamp partition with Parallels, Windows notices you have different hardware (as it's now virtual) and wants reactivation. As long as it's activated in both Bootcamp and Parallels, then Parallels should keep track of the activation and allow you to swap between Bootcamp and Parallels without reactivation. You can check Windows activation be clicking Start, right click Computer, properties and scrolling to the bottom of the window.
You can increase the RAM allocated to your virtual machine by right clicking it in the Virtual Machine list window and selecting Configure. The General tab allows you to increase the RAM allocated. Find a level that keeps both OS X and Windows happy!
Hope this helps,
Daniel
