You have the right to remain silent. Do it! Most of the people in prison talked themselves into those cells. No talking means no Facebook conversations. No tweets. No letters or phone calls from jail speaking of your case. No coded messages. No jailhouse lawyers or bunky discussions about your case, even if you trust him! No talking!
Gather your evidence. Get the names and contact information of your witnesses. Copy texts, email and Facebook postings that support your case. Read your police reports and be prepared to discuss your case with your attorney.
People who make appointments to see their attorneys get better results than people who wait until the day of trial and meet their lawyers at court.
