I have the grandfathered unlimited data plan with AT&T. Does anyone know if it will allow me to set the 4.3 phone as a hotspot without incurring additional charges?
 
You won't be able to use Tethering at all, unless you forgo your unlimited data plan and hop into one of the Tiered plans.
 
No, I don't believe so. The hotspot is an added feature + fee. I'm sure jailbreakers will get around this, but the official way cannot.
 
My question is if I want to get the tethering plan do I have to give up the grandfathered unlimited plan in place now?

Yes, you do. You have to go to the $25 2GB plan (and add the $20 tethering plan which gives you another 2GB).
 
Just jailbreak when the 4.3 JB comes out. It'll probably only be a week or two. Then you can keep your unlimited plan and tether for a one time fee of $2
