According to your last statement above, if the car rental company will allow you to rent a car with a traffic citation in lieu of your regular license, they require that the license be valid for the whole rental (they would consider your court date to be the expiration date of the permit and your rental must end before this date). You would have to contact the rental car company in advance to determine what would be acceptable as a second form of photo ID with signature.... some common ones that most often accepted would be a passport or company id card with photo and signature.
Here is the basic information provided by some car rental companies regarding their policy on the ability to rent a car with a traffic citation or to rent with a temporary drivers license. (links open in new windows) Note: some companies are not completely clear on the policy with regards to traffic citations specifically...(and policies are subject to change without notice) you should always contact a company representative for clarification before renting, to make sure that you meet all rental requirements and/or if you have any questions about car rental policy.
