Unfortunately I have alot of experiance with the cops and the courts. Keep postponing dates. They will get sick of u. Believe that! Also I don't know what jurisdiction you're in but I many bud cases and never was ordered to pay court costs, except for a disorderly conduct cuz I told a cop FUCK YOU BITCHES. Also get a affidavit from your buddy who'll take the rap, & have it notarized. Give copies to the D.A. No one wants to go to trial No one!
