Check out the 'Astral Projection' links in the Tutorial forum, the resources these lead to ( in particular the downloadable e-books ) are a great help in clarifying the right steps to take. [/b]

Yes, the downloable treatise on AP is, in my opinon, the best resource you'll get for it. Covers everything- chakras, planes, troubles you may have, any "dangers", the alice in wonderland effect, and includes meditation techniques and ways to improve it. Pretty much holds you hand at the start, even with no skills whatsoever, until you reach a point where you can DO IT, and then it goes into depth about all the things you can do and experience.

OH, and dude, that was your heart chakra. And that's good. That's good!
