I have a Trek 5200 that uses 700x23 tires.

When buying a replacement tube, does the 700x23 apply to the tube size also?

Also, do I need long valve or regular for the Bontrager RaceLite wheels?
 
Pretty much the tube size follows the tyre size,
700 or 28 x 19-25 tube is normal for a 700x23c tyre.

Yes, a Longer valve, around 48mm, is better for the more Aero rims.
