I think you are confused. As you pointed out, your six months has already passed for purposes of the divorce action you already filed. Changing the action to summary dissolution won't make any difference in terms of moving your case along any faster. You have made several mistakes which have resulted in a rejection of your paperwork. This would be the same result if you were to make mistakes with your summary dissolution paperwork. I think the better plan would be to hire an attorney to handle the paperwork for you and get it done right once and for all.
If your petition has already been filed, you should proceed as an "uncontested" divorce. Based on the facts you've provided, your divorce can be finalized fairly quickly. You should probably hire an attorney to help you prepare a judgment packet.
