Tearing the colony apart, there are no guarantees you'll get the queen. There are going to be alot of bees in the air, and if you can remain calm and deliberate, you may find her on the combs as you transfer them. After you shake the remaining bees out, take a moment to look for any clumps of bees on the grass, on the outside and inside of the old hive. Look in the evening again, and the morning. The queen could be anywhere and she will usually have an entourage. The pics that Jay posted show the rubberband method, which I think is by for the easiest. I would probably scratch the caps on any large combs of capped honey and put it across the yard so they start back working, collecting the honey and building comb. Just don't pile it in front of the new hive. This may incite a riot, and any colonys within flying distance could crush the new hive while it struggles to get organized.
Good luck getting them situated. I went a while without bees in the yard, and didn't realize how much I missed them until I got them back. It's amazing when freinds come over for a beer and barbeque, very nervous about the squadrons of bees zooming everywhere. Usually before long, they are relaxed and asking all kinds of questions, which I answer at great length because I love talking about them. I've got almost a dozen colonys in various people yards the last couple years. Those suburban colonys are my most consistent producers.
