While we don't like to spoon feed people, it doesn't hurt to ask for others to point them in the right direction (which is what I believe Darkened Rose is asking for).
For elemental magic, there is a coven here listed under the Group tab near the top of the website titled Elemental Magick. Please keep in mind that elements aren't just forces of nature; they are the building blocks of the universe; each mindset has a different idea of what said elements are. I would suggest looking at the elements of different cultures in their spirituality and philosophy and then research further what pulls to you most. Be sure to to validate your sources, cross reference, and learn the original context of each cultural idea.
The same goes for projection. It is not present in every culture, though it is very popular among Occultists. Most identify multiple types of projection and even the idea of projection can change between people (common ones are the shifting of consciousness and the separating of a part of the spirit and the physical body). I think it would be best to learn about Subtle Body Theory, in which we exist in all planes of existence at once. While this is not true for everyone, it gives you a starting point for a cosmological model to work with and better consciously understand a matter not akin to the conscious mind.
