Why pre emergent to revive?? This is for killing weeds and/or other plants.
Fertilizer, water, aerate, top dress.

Yes, the st Aug will fill in after the growing season starts. Push it with fertilizer, water, and frequent mowing. If you don’t want to wait for that small to fill in, yes you can sod. It will be quicker. No need to topdress. Do not aerate.

Fertilizer and water will go a long way once the growing season starts, especially if this area gets enough sun. If soil temps are 65ish or higher I’d throw down 0.5-0.75lbs N per 1000sqft. If you’re lower than that I’d wait a bit. Reapply every 30 days during the growing season. You could add plugs to the sparse areas to speed the coverage up. As the other comment says, you should focus on getting good ground coverage and a healthy lawn before hammering herbicides, including preemergent. Not the end of the world if you already put it down but I’d give it a solid year before applying preemergent again. Spot apps of post emergents would be appropriate but I wouldn’t blanket until the lawn is more vigorous and healthy. Once the grass is growing you should mow tall and frequently, following the 1/3 rule. St. Augustine likes to be above 4” so ideally you’ll mow at the tallest setting when the grass gets about 6” tall.
