Hi Tom
There is no substitute for practice. IMHO if you are using a manual Dob, there is no substitute for a good star chart. I use Uranometria Vols 1 and 2. Very detailed maps and you find them invaluable in locating objects. A set of star charts such as these

help in orienting yourself and finding the bright stars needed to get you close so you can then use the U2000 charts.
Sky Atlas 2000 is also highly recommended but I have not used them.
I also use the Deep Sky Observers guide as a guide to objects to look for.
But remember, there are no shorts cuts to learning to navigate manually, only practice!
