This came up in a campaign I was in. Here's a tip that's simple and cheap (always a good combo).
Write up a short blurb on every PC on separate 3 by 5 index cards. Include stats like AC, Search Spot & Listen, Initiative and any special abilities. Do up cards for the monsters. At the start of each combat, go around the table and ask everyone what they rolled for initiative and assemble the cards in order. Roll for you bad guys and insert their cards in the proper spot.
Nobody gets forgotten and you have a handy reference for common combat and adventuring stats.
