Sean,
Does the flash fire repeated bursts? If so, what you're describing sounds alot like the built in flash's AF assist. That goes right in line with your lens not being able to focus also.
Was it a dark area you were trying to focus on?

I'd have to agree with Roger on this. It sounds like the Auto Focas assist flash (where the flash illuminates the subject so that the camera can obtain proper focus). I'd suggest trying to repeat your portrait session in a better lit area and see if the focus problem persists (the AF assist flash my still fire, but you should be able to obtain focus thereby shortening the AF assist burst).
I don't know if your camera has a DOF preview button, but mine fires a nasty modeling light by default (disabled now) so it may be worth a look.
