You would pick up 2 loot at the start of your turn, then rest. On your next turn, if there is still loot in the room, you can pick up one and take your normal turn or rest and pick up 2 more loot.
Belkar gives Durkon ANY loot card. Actually, Durkon and Belkar don't need to discuss what loot card he'll give him. The intent of the shtick is that ANY loot can be given to him - not necessarily just loot he drools over. Durkon shouldn't expect to get loot he drools over.
