Brendon,
I "second" the recommendation made by Frank II. Reading ETBD will be the most important first step in your planning.
You didn't indicate how long your trip would be? In looking over your list so far, my first impression is that you haven't allowed enough time in some of the most important cities, Rome and Paris. Therefore my first critique would be to expand the time to 4-5 days in each city if possible. There's LOTS to see and do!
It would also help to have some idea on what your plans are for Normandy? Two days is enough for a quick overview, but good planning will be essential!
What are you planning to see in Bavaria?
Given your location (I'm assuming Auburn, WA?) I'm sure you'll be able to watch Rick's shows on KCTS, so you may get some further ideas there.
I'm sure the group here will be able to offer lots of suggestions, but we'll need as much information as possible to work with.
Good luck with your planning!
