Elemental Invocations Options

Hey, I'm looking to start working more directly with elemental spirits, and I'm trying to figure out some things to start off with... for instance, what elemental is easiest to work with at the beginning, what tools might come in handy, if there's any formulas that anyone has found work particularly well for them that they may be willing to share? Anything that anyone can lend would be very very appreciated, thank you (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/wizard.gif)

Thank you:) Well, I will start off by saying that personally I am not a big fan of high ceremonial rituals, I'd prefer to work with this from a more earth-bound, possibly celtic or shamanistic perspective. My objective isn't actually that direct, (IMG:style_emoticons/default/hmm.gif) mainly I would just like to see what I can learn from the experience (everquest for knowledge, yknow). I've always felt more connected to the idea of working with the elements as an external force than with deities and such. I'm one who feels more comfortable outside in the middle of the earth's forces than at a temple, and I would just like to learn more about working closer with that.
Sorry for the rambling:P Bit of background there.
Anyway, if there's any help you could give I would appreciate it. Thanks again.
