Re: G and Gnaught
Go is used when you are talking about the reaction at STANDARD conditions, like 1 M or 1 atm, G is used in other situations.

Re: G and Gnaught
1. deltaG is the change in Gibbs free energy for a system at non-standard conditions. At equilibrium this value is zero.
2. deltaGnaught is the change in Gibbs free energy for a system at standard conditions (298 K, 1 atm pressure (constant P), 1 M concentration of all reactants). This value is not zero at equilibrium.
*The delta Gnaught equation is derived from the deltaG equation, because that value was placed at zero for equilibrium.

Re: G and Gnaught
Anything with the naught sign indicates standard conditions! The good explanations above would also apply to things like E vs E naught :)
