No it's not Reede Smith because Red John is possibly his partner Gabe Mancini 
The clues are 
HE IS MAN=He is Mancini
666=He is called Gabe Mancini for a reason just like Red John and Carmen Lee it links to the 666. Bruno Heller wrote him in so he knows his name links to 666 so why have that name which not many people notice and not have him appear so far.
Bertram also=666 but he is at the top of most peoples list and when you look at the 666 theory not many people will notice Gabe Mancini just Gale Bertram. So why would Robin Tunney be shocked that its Bertram but she would  be shocked if it was the guy she did one or two scenes with in season 5.
He fits all the descriptions and he is the right age.
If he is RJ it explains why Red John never killed Lisbon.
After reading all the theories about 666 it just has to be someone who links to it.
