Preen normally only helps with new weeds that come from the top (ie: seeds floating in the air, etc). It is great to use, but it won't kill any weeds that already have a root system started. If you have missed any while pulling, then they will continue to grow. If you are going to wait to plant, then I would suggest CAREFULLY applying a Round-up type product to the area to kill weeds that are existing. It won't work until they show their little heads, but that will get rid of them. Usually an area like this is still able to be planted approx 3 weeks (or so) from Round up application. I use this method in my veggie garden. For instance, I am tilling up another new area for next spring. I am going to Round-up the grass, till- it about a week later, then apply round up again this fall. Once it gets warmer, I will round up one more time, then till some Preen into the soil, and then plant.
