The NAB website has some decent planning tools. You can look up an exhibitor, see where they are on the floor plan, and make a list of which ones you plan to go to.
For hotel prices, I go to travelzoo. You can find some good deals there, some deals are better then the NAB housing site. I like to stay the Signature at the MGM. The Signature is a very nice all suite tower of the MGM, and is located in the back of the MGM by the monorail entrance. The Monorail is far cheaper and faster then taking a cab on monday morning of NAB.
