How quikly you can get/find and print the following manual hard copy from Oracle/Oracle site ? Just to startup. This one is good. I was more DBA on Unix Platform. It did help me a lot on NT to start with.

For the rest of the stuff Generic documentation 'Adminstrator Guide' would do.
Not that you couldn't do it yourself, but have you thought of getting a consultant for a couple of days? In a couple of days you can have your database up and properly setup and you will get about 2 months of experience just by watching.
