I agree, issues need to be brought to light and dealt with and then you do the wedding/recommitment ceremony. However, I do agree that once you reach that point, a new ceremony is a good idea. At Retrouvaille (have you heard of it? GREAT for communicating as long as both parties will do it), there are even some passages recommended for re-committing.
I will say it was a heads-up in my case that when my H wanted to come back home, I asked him to renew our vows, even if it was just the two of us and no one else there. He said it 'wasn't necessary'. Should have tipped me off....
Keep the communication going, you are making headway.
