Mary, simply go through the rider with a Black Sharpie and draw a line through the requirements you are unable to meet, or consider excessive, and mail it back. Usually they'll sign it and take the gig.
Those things are put in just to see how far they can go.

My agent used to book major acts for large venues, and she noticed after a while that the the performers never touched the stuff in the dressing-room (bottles of Jack Daniels, cases of beer, sandwiches, etc.), but the roadies grabbed it all when the gig was over.
