Show up for your court date and bring valid copies of any documents you did not have with you that you got the tickets for.
Speak to the prosecutor before trial and see if they will drop the document charges if you plead guilty to the stop sign and speeding ticket charge. And see if they will reduce the speeding ticket down as well (does not hurt to ask).
The prosecutor has no obligatio to offer you any deals at all, but a lot of times they will drop paperwork tickets for guilty pleas on the other ones.
If the prosecutor will not give you any kind of deal, then say you would like set another trial date and get disclosure so you can seek legal advice.
