Meurphy,
Memory Optimizer Course would probably help you w/ memorizing your lines.
But any book on memory by T. Buzan would also. So would the Silva Methods.
And, the cheapest of them all would be to use the LS paraliminal: Memory Supercharger. That is one terrific tape. I've never heard anyone say they haven't benefited from it.
Tape your lines in your own voic saying them the way you want to. Then put that tape on a recorder that plays continuously and go to sleep. Trust me, you'll be happy w/ the results
