I found that as I dealt out cards to each player, I wanted to deal out cards to each group of monsters. I initially had trouble keeping track of what monster group had what card.
Then I struck upon an idea -- make cards for each monster!
Using godeckyourself.com I made a set of monster cards. Some monsters have more than one card because they are complicated :( but that's OK.
Here's what it might look like on my side of the table after I deal the cards --
Each player gets a card then I deal these out in order at the end. Works well and serves as a visual reminder of who has gone and who still needs to act. The card is removed when the monsters turn comes up.
