Yes, almost all UTP terminations are "B" configuration. Are they not already terminated? I'm not sure why you would need to punch the cable in the wall sockets. The other end is mostly likely terminated on a patch panel in the maintenance closet (like you said), and if they'll give you access it shouldn't be a problem. Also, if they aren't labeled you may need a tone and probe kit to find the proper jack on the patch panel. Distance can come into play too. If your apartment is over 150' from the maintenance closet, you probably shouldn't even bother (cat5e tops out at approx 300', so directly patching one jack to another can exceed that limitation).
