These things take time. That being said at some point soon (in the next couple of years) we will have to deal with Iran. If we are successful in Iraq that will deal a huge blow to the Mullahs.

True, these things do take time. But I think you have the sequence of events backwards. Considering that Iran and Syria are the principal pot stirrers in Iraq, I believe that success there is largely contingent on America forcing the mullahs and Bashar al-Assad to stop their meddling.
In other words, addressing the Iranian problem after we succeed in Iraq is a strategy for not succeeding in Iraq.
