Yes, you will want to speak to your attorney about the sequence of events to see if they collected any evidence that can be used against you and if so if they violated your rights under Miranda. Generally, once an accused has invoked their right to remain silent, the questioning must stop. So, unless they came into the room and only asked you if you are sure that you do not want to waive your rights, then it is likely that any questioning without a specific waiver on your part, and evidence gathered from that would be suppressed.
In any event, you must speak to your attorney about this since they are the ones who will have access to all the relevant information and evidence and can determine if your rights were violated. Ultimately if the police took items that are not related to a crime, you will have them returned to you.
