Wow! Loaded question.
IMHO, the most important thing is to have a RULE of prayer and to not deviate from that. Determine the times that you will pray (immediately upon rising from bed, before going to sleep, e.g.) and do so with conviction (i'm sure you do).
As to whether music is playing or not, I prefer not to have it on simply because I chant the psalms and hymns of the office of Compline. Having the CD player and me going on at the same time would be very confusing. If you can learn a little chanting, I have found that it enhances my prayer and contemplation.
Also, there are certain prayers that are so traditional and beautiful that you should memorize them for use at any time (e.g. parked in a car during rush hour traffic and your AC quits on you). Learn the Trisagion, the Great Doxology, Psalm 50, the Prayer of the Hours, "It is Meet" and the Troparion to the Theotokos. Those are just suggestions, but I think they are a good starting point.
HOwever you pray, remember to make prayer your own. The words may have been written down by a saint, but they're not copyrighted! Say them with compunction as if your own heart were uttering them for the first time. That way, the prayer never gets old and it is always reverently offered.
I hope I gave a few suggestions. It is a loaded question. I know that when I was inquring, I was desparately trying to get my hands on anything related to how to pray and what to pray. And though it was a good thing to search for such material, a priest reminded me that you always have the Lord's prayer and the Jesus Prayer.
