I know OrCad 9.2. The best way is to use the help file. On layout, there is help, read it and practice.
If you are starting from scratch, consider Eagle. You can download free from Cadsoft the two layer trial version. It is not close to as good as OrCad 9.2, but there are good people like Keith here that can help you. Also, there are a lot of Youtube instructional videos you can get start. I learn it this way. I doubted you can get as good a support with OrCad 9.2 as it is 10 years old already.
