Glad to hear you like them! I'm afraid I don't know the exact length of the cord since I haven't opened it. I'm going to say it's the standard length of about 3 feet. If you're worried that it might be too short for you, I've read that there are audio extension cords that you can use to make it longer. Hope this helps! :)
Sure, if you win, I'll send it to you. I think a lot of sellers won't send you the item if you don't have a verified address, though. Sometimes the item gets lost in the mail, too.
I believe the plug is a 3.5mm phone connector(also called a minijack plug), and is the most common type of plug for this type of earphone. It's the industry standard for personal devices, such as the Ipod, a portable CD player and stereos.
