You may regret stepping foot over there, but HeadFi is the go-to internet resource for headphones. Some looong threads, but also some people who know their stuff.
With your requirements, you will need closed headphones. Too much leakage in and out for open cans to work for you. Open headphones are generally considered to sound better than closed, but they aren't great for use outside of a quiet space.
Another thing that will help folks give good recommendations is whether or not you plan on pairing them with an amp (and there are some nice portable headphone amps out there too). Some cans will need more power than an iPod etc can provide.
Lastly, what are your listening preferences? Both in terms of genres of music as well as what you mist listen for an appreciate when music is playing (bass? treble? soundstage? dynamics? transients?)
