For 1 and 2, the letter used references DV 2012. Disregard.
For 3 disregard as they have the medical report, if you sent it with application.
For 4 if it was certified by your embassy you are okay.
Notarized copy means a notary public( somebody with the states permission to certify your documents), they date and stamp docs saying they are a notary public. If the letter states a notarized copy of passport then have them notarized. If not you do not need to notarized passport.
