There is a lot of law, both cases and statutes, that you would need to know to have a chance at pursuing a successful stop motion, and no one can give you the benefit of three years of law school, not to mention years of experience, in a web post. The real question you need to ask yourself is can you afford not to have a lawyer.
This answer is provided for general information only. No legal advice can be given without a consult as to the specifics of the case.
A mistake of fact may be a constitutional basis for a stop. In other words, it is againt the law to have a suspended registration. Because having a suspended registration is against the law, the officer may pull you over if he mistakenly (and reasonably) believes your registration was suspended. If the officer had made a mistake of law (i.e., if having a suspended registration was not against the law), then the stop would not be constitutional.
Whether the officer had enough information to get all the way from stopping you to arresting you is too complex of a question to answer on Avvo. Further, to answer the question, an attorney would need much more information than you can/should post online. Anything posted online may be used against you in court.
Frankly, this is the type of information for which attorneys are paid. You may want to consider purchasing a few hours of an attorney's time to review the case and see if there is a viable stop motion or other motion to suppress. Then, you could decide whether to hire the attorney to represent you in court.
Good luck, and Happy Holidays!
A public defender is an attorney and she will be familiar with the relevant law. If you are not comfortable with her representation, you'll just have to make your criminal record a financial priorirty and find a way to retain private counsel.
The short answers are 1) it would be unusual for the officer to issue a citation for the underlying traffic violation and 2) if the officer reasonably believed the stop was valid, the stop was valid even if he was mistaken.

I believe that your 4th amendment rights would have been violated if an officer falsely believed that your suspension was registered (assuming that this was the sole reason for pulling you over), provided that the police department as a whole already knew the correct information, i.e., that it was actually reinstated. But in a scenario where you had just reinstated it and that fact was simply not yet reflected in their computer system, the officer’s mistake might be reasonable, and a judge might disagree with me. The concept of the “total knowledge of the police department” is frequently used for the benefit of the police when, for example, one officer, who has probable cause, radios another officer (who does not have probable cause), to pull you over. That would routinely be considered a good arrest. In the reverse situation, however, there is no good policy argument that same concept of “total knowledge” should not to be used against the police when they make an unreasonable mistake. That would be when they were in possession of the information that you were reinstated, yet acted upon stale, erroneous information that you were not, when they pulled you over, assuming that a reasonable time had passed since reinstatement (i.e., it available to their computer system). It is therefore probably worth your while to retain an experienced criminal lawyer in this scenario.
