Integrating ssd to system help

Hello. Ive purchased a new intel 510 120 gb ssd and have been looking around the net for instructions and Im even more confused then when i started. Here is what i want to do. I have Vista 64 running my system on a 500gb hard drive. I dont need tons of storage as I only really use my rig for a few games. I want to install my os on the ssd. is it possible to keep what i have on the original hard drive and delete the opertating system and still be able to load the games and programs on the old drive? Can i migrate certain programs to the ssd? Are there any guides that can help me with what im looking to do? Thanks for any help.
