Please take all precautions you can... sounds like you are in for a rough but not overwhelming weather. The surge is usually much less on the southern side of the eye and, as has been said, will come from the land side with the winds.
I would think the main problems will be power out and water gone for a good while.
Good luck to all of you and can't wait to hear that you all came through just fine!!
We're praying for you in SC!!
