The only problem I see for you here is that you admit that your passengers side widow is ILLEGALLY tinted. Based on your statement that you passed the officer, I assume that he would have been on your passenger side. Therefore seeing the ILLEAGALLY tinted window giving him PRABABLE CAUSE for the traffic stop.
As far as all the other things you endured, a Field Sobriety test is subjective at best, any officer will tell you that. This is why when they feel that you have fallen outside the parameters set forth by the law and their training, additional tests are preformed. The blood test you submitted to will show if you were under the influence or not and will be admitted at court. If it proves that you were not under the influence of either alcohol or ILLEAGAL substance's several things could happen.
I would advise you to seek legal counsel along with the Internal Affairs Dept. As you have already been told you do not have to be Mirandized until an interrogation begins, or you are notified that you are being placed under arrest and WHAT FOR. Once they decided to handcuff you they had every right to search your vehicle.
The only Question that comes to my mind is:
If you knew this was a high crime area, and it was after dark, Why were you there?
Good Luck
