Thanks.
The Shimano-Europe site has lots of exploded diagrams of different parts. It's usually the newer parts, so you many not be able to find
your derailleur, but it can help. Here's one for a slightly older 105 derailleur:

By "cogs", do you mean "derailleur pulleys"? They're usually the same size. Only rarely are they different- and usually the bigger one goes on the bottom or farther away from the derailleur body.
