Yes you can still plead not guilty. The plea isn't saying under oath that you didn't do it, just that you aren't going to voluntarily accept the guilt.
Confused and ignorant is MORE than enough reason to get a lawyer.
Any pretrial or other diversion option is WAY better than getting a conviction for this. Unless you are sure you know what is going to happen in the specific court you are appearing, having the advice of a lawyer would be preferable. The diversion options seem to vary by county to county in Florida, but they involve six months of keeping your nose clean, possible drug classes/treatement (and you can assume TESTING) , and some community service and paying for all of the above (several hundred dollars).
