Warren has given you very good advice. If I can chime in here, you might want to get the Peterson Field Guide to the Stars and Planets first. It's a fat little book that works very well with binoculars, and I still use mine from time to time, though I have Tirion's charts, his large wire-bound atlas, and his hardbound Uranometria.
Get a pair of 7x50 binoculars first. If you want great quality, you should buy an entry-level pair from a company that is known for quality. I have a basic pair of Nikons that are simply wonderful. The reason I suggest this is that Nikon and other companies that make high-end optics have superb quality control, and even their entry-level binoculars are great. Don't try to skimp on these too much because if you are like me, you will use them during almost every observing session with your main scope.
Good luck.
