welcome! where are you looking to get certified?
t-bone's gear recommendation if you want the best and to buy once cry once
Deep Sea Supply BP/W-$500
Deep6 Doubles Reg Kit-$850 yes I recommend doubles despite most people diving singles because of the potential for pony bottles, sidemount, and most important so you don't lose a dive if you have a first stage failure.
DIY slate for compass
Wetsuit-get whatever fits
Fins-Deep6 Eddy or Dive Rite XT
Booties-NRS Paddle Wetshoe
Mask-DGX Ultraview
Snorkel-don't bother unless you're snorkeling, in which case get whatever is cheap and simple
Computer-Hollis DG03, Deepblu Cosmiq, Dive Rite Nitek Q, Shearwater Perdix. If you want AI, and/or want the best, get the Perdix, if not, then the others have pros and cons.
Deep6 is in Macon GA btw so very close to where you are. HOG is as well though the only thing I'd probably recommend buying from them is regulators if you don't want to spend up for Deep6 which are similar, but better
alternatively, when I'm back from the UK, if you have any reason to get up to Greenville, I'll be able to show you just about any piece of gear you are thinking about.
as an extra alternative, if you want to get certified in the springs, contact Cave Adventurers because they teach OW in both backmount and sidemount. If you go backmount, I'd recommend getting the DSS BP/W, booties, and DGX mask before you go down, and everything else you'll be able to test dive after your course with them before you commit to buy which is a nice perk that really separates that shop from everyone else
