being a newby monk myself, (I have just ascended a couple of days ago) I asked the same question, and got a lot of answers.
I decided to go for Mo/E, basically because of the "glyph of lesser energy", which really helped with providing me with more healing power.
After ascension I have tried Warrior, which I did not like (probably not the right skills yet), but am now running around with a Mo/Me, and to be fair, I love it, I am using Energy Drain (Elite skill), and it is really very spectacular, draining the baddy of energy, and making it available to yourself.
In the end it depends on what kind of monk you want to become though. I have concentrated on Healing, and I have to admit, I really enjoy it.
hope this helps, this is obviously noob advice
Enjoy
