If you are wanting to create a Flash intro for your web site, you will not need something as detailed as a Flash Remoting or Cold Fusion book. Something like the Flash MX Bible should give you a good start. It has a lot of basic to intermediate chapters and a couple of advanced chapters. Should be plenty for you to learn how to build a Flash intro and more. Covers Flash terminology, a fair amount of actionscript, sound, video, and compression.

Good luck,

Scott
