Found some info on rares. Seems kind of complicated and depends on the packs you are buying. This site has lots of info and links on it:

Basic info:
http://yugioh.wikia.com/wiki/Booster_Pack

Detailed info (with some stats for each series etc...):
http://yugioh.wikia.com/wiki/Rare - silver card name and the image is not holofoiled
http://yugioh.wikia.com/wiki/Super_Rare - black or white card name and the image is a holofoil
http://yugioh.wikia.com/wiki/Ultra_Rare - gold card name and a holofoil image
http://yugioh.wikia.com/wiki/Ultimate_Rare - "embossed" foil on the Card Artwork, including the borders of artworks, Attribute icon, and on Monster Cards, the Level Stars. The card name is printed gold, like an Ultra Rare. When scanned, the embossed image may be muted and the image indistinct from the background

As for official prices, I don't know ...
