With a red-light, and a police officer with a stop sign.

Probably not. The officer's signature is usually where he certifies and swears to the complaint on the citation.
not really, they will write you a ticket and if you do not agree you can go to court.
If a police officer doesn't have a person to sign their ticket, the ticket is still valid in any state. It is only a myth that the ticket will be thrown out of court.
You can do it anytime by going to your nearest police station. In most cases, you can sign up there. In some cases though, they don't accept sign ups in the station and would direct you to the headquarters. That should get you started.
You must obey the police officer over the other three signals. Police officers have the authority to direct traffic and their instructions should be followed to ensure safety on the road.
California has a 3-1-1 service (Non-Emergency Police) that is perfect for these types of situations. Simply record the licence plate, color, make, and model of the vehicle and file a Police Report. The Police will either ask you to sign the report (making you a "Police Officer") or fill out some more paperwork to issue a non-moving violation.
You could always argue that the ticket was not properly issued in accordance with law. However, you must prove that the law requires police to have a motorist sign a ticket.

You must obey the police officer over the other three. While red lights and stop signs indicate traffic rules that must be followed, a police officer directing traffic has the authority to override those signals for safety and order. Always prioritize the officer's instructions in such situations.
