Another is to have no cross table metagaming discussions or suggestions in combat outside of a player's own turn in which case he can say one thing.
So, "Fred, help me flank this guy" or "Barnie, use your Lightning power on the Vampire" is ok. Making two suggestions (or three or whatever you think inappropriate) is not.
Carefully explain the situation ahead of time and explain that you will be enforcing it by having the player who either makes too many suggestions on his turn, or the player who makes a cross table suggestion, do a melee or ranged basic attack on his next turn.
I have a player who does this as well. It's a bit annoying that he won't just let the other players play their PCs. My issue is different than yours, but it boils down to some people having to influence the game out of character.
By limiting the suggestions to player's turns, it not only speeds up the game, but it also forces the less tactically minded players to engage a bit more (as opposed to them allowing the other players to figure it out).
