Stephanie,
A few thoughts on your questions....
1.) Could you clarify your statement "The 1 day tours is not complete"? The best option would be to plan at least one night in Bayeux and take a BattleBus tour. The WW-II sites cover a large area, so the best you can hope for in a short visit is to get a brief "summary" of the important sites.
When do you expect to be in Normandy? Keep in mind that this year is the 65th Anniversary, and that's going to be a VERY busy place. I doubt that you'll find many Hotel vacancies in the area, and some of the tours will probably be suspending operations for a few days around 6 June so their Guides can attend the ceremonies.
Regarding "English speaking driver", you might check the France Guidebook as there are a few listings there for Guides.
2.) Can't help with that as I use budget Hotels.
3.) You can't "jump queue" at the Eiffel Tower, you'll have to wait in line with everyone else. Note that to go to top, there's an extra charge. You can minimize queue times to a slight extent by choosing the time of day that you visit the tower. You might try later in the afternoon or very early in the morning, as queues might be a bit smaller.
Regarding the Louvre, as the previous post mentioned a Paris Museum Pass will definitely help, as you'll be able to use a separate queue (there may still be a short wait). The Louvre is enormous so you may want to focus only on one wing (perhaps the Denon wing where the Mona Lisa is located). You might also enjoy the Musee d'Orsay or others (may as well get lots of use out of the Museum Pass if you buy one). The view from the top of the Arc de Triomphe is also awesome - provides a great view of the Eiffel Tower, which is great at night when the strobe lights are flashing). As your husband is a "war buff" you might enjoy the Invalides also. Lots of WW-II displays and an awesome Cathedral.
Happy travels!
