CCFL's are a thing of the past, check out the xbA LED rings over at TRS. They'll knock the socks off any other AE kit(led or ccfl)...just keep in mind that the install will be more involved as they are not vehicle specific.
As far as opening up a permasealed housing, if you haven't really tinkered with headlamps before they can definitely be a challenge first time round. Just take your time.
