Why do you think these two are separate. Just talk to yourself and learn to listen to your inner voice. It's that easy, you seem to try to make everything a hard task here, possibly you are over thinking things. Just do what comes natural. You have intuition, you have gut feelings, both of those is your subconscious communicating with you. Proyect_Outzone did a great post a couple of days here about listening to your inner voice. Here is the link, try it.

Try looking around this site a bit more, you will find helpful Primers and writeups by some of the people here that Phase/OBE regularly. I would start with the entire Frank Kepple PDF created by Xanth if I were you. He answers hundreds of questions in that one. You need to show your level of commitment to success, this comes by doing a bit of reading, you will find this will answer many of your questions.
Good Luck
