Yes you will definatly need to bring all proof if you mention it as it's often asked if you disclose it. If you do not it's rare that they will ask for it, unless there are other concerns with your N-400.
One easy way to determine if you should or should not mention them is by how complex your N-400 is. If you have nothing unusual, long stays, any criminal records etc, then in most cases you don't need to mention them.
If you have a lot of tickets, or have had some convictions or been to court for lawsuits or been away for a long peoriod out of the US, then you might want to bring them to prove that you are upholding US law by paying them.
Really though, as the 1-800 INS people stated, the lawyers I talked to stated and my own interviewing IO stated. No you do not need to disclose them if they are under $500 and non-DUI. The only time I've heard people saying you must disclose them are common users on this board, never from the professionals or the INS themselves.
But it's up to you, it doesn't hurt, but it can be time consuming if you have to go find all the documentation on all your tickets from all the places you got them from...
