Were you doing any managing at all...if yes was it more than 50% of your work?
Ok, so you were misclassified the entirety of your employment. You cannot agree to waive your hourly non-exempt status. You are owed overtime compensation at 1.5 times your average hourly rate, which basically wold be the weekly pay divided by hours. Your concern appears to be that you have no idea what hours you worked. That's ok, because the law put the burden on the employer to keep track of your hours...they fail to count your hours at their own peril. What you have to do is basically come up to the best of your recollection what hours you worked per week.
You should calculate the best of your recollection how many hours you worked in each of the weeks. Then take your matter to an attorney. Because you also have the vacation issue, it is better an attorney handle it than the Dept of Labor, which does not generally handle vacation claims. Likewise, you're owed attorney fees and double damages on the misclassification matter.
