I haven't looked at the EEPROM dump, so I can't help you with that. Perhaps someone else can.
One place for various adapters to program chips is MCU Mall. I have purchased from them a few times. http://www.mcumall.com/comersus/store/LeftStart.asp?idCategory=30 It they don't have the size SMD clip you need, you'll have to Google. I bought a few elsewhere years ago, but don't remember where.
