It seems like you have a good grasp on what to expect on your trip which is great. I would suggest going to the hotel and saving the GTNP visit on your way to the airport.
Lamar Valley is a pretty big area and it's best to visit it early in the morning or at dusk as bears and wolves are most active at that time of day. If you see a bunch of people with spotting scopes and large camera lenses standing by the side of the road they are most likely observing one of those big animals.
If you want some books to help you with your trip, Yellowstone Treasures: The Traveler's Companion to the National Park is a very detailed one. For day hikes A Ranger's Guide to Yellowstone Day Hikes book is good and Trail Guides Yellowstone web site is an excellent source for all things Yellowstone.
