Yeah, the "all about aya" thread that xtechre posted a link to is very helpful. Starting with Caapi only is very helpful and reassuring before starting journeys with DMT added. But what has helped me the most is reading as much as I can find, and spending a lot of time going over my intentions and deciding why exactly it is that I want to drink Aya, why I'm so interested in it, and how it can help me. And as was already stated, start small. It's a good idea to brew a little more than you'll need, and start small - waiting for effects before drinking anymore if you feel it's right. You can always drink more or try again another time.. but if you've taken more than you might need at that time, the realization that you still have several hours to go can be very scary.
