A couple big safety things to remember: Make sure the turkey is completely dry before putting it into the oil. Any water will make the oil splatter. If it splatters on you, you may drop the turkey. If you drop the turkey, oil will splash out of the pot and catch on fire. You can guess how it goes from there.
Before anything else make sure you haven't overfilled the pot with oil, remembering to allow for expansion when hot. Some folks recommend filling the pot with water before hand and then sticking the turkey in there to see how much water is displaced. Once you take the turkey out you can figure out to what level you can safely fill with oil, taking into account head space for any bubbling and for expansion.
Don't even think of doing this on a wood deck or, heaven forbid, in the garage. Lots of folks have done that and lots of houses have burned down. See the first tip to figure out why.
On the brewing side of things, be prepared to spend a lot of time getting the pot degreased before the next brew.
Good luck with the turkey. If I lived in the same town as you, I would probably invite myself over for a bit of that.
