How to solve this thermodynamics problem?

Consider the following equilibrium at 1325 Kelvin: 
S8<-->4S2 

(B) Suppose that a mixture of gases is produced at the same temperature where: PS8 = 6.8e3 atm and PS2=81.6 atm. (1) Calculate the reaction quotient, Q; (2) determine whether, for these conditions, the reaction is spontaneous to the right (R); spontaneous to the left (L); or at equilibrium (E); (3) calculate the value of Kc, and (4) calculate the value of DeltaGo 
Correct answers: 
Q = 6520 
Reaction is: L 
Kc = 1.26e-4 
DeltaGo=-56 kJ/mol  

I understand how to find the Q value using the pressures. Can you please explain how to find the Kc and DeltaGo values? Thank you so much!
