If you ever can't use the reflector, due to size, wind etc. I'd still try and shoot without flash, definitely without on-camera flash. You can even buy a white poster-board and use that (cut it down in size); It would be easier to hold and still produce a bit of reflection. It may have not been necessary at all. I shot an indoor newborn session, without sufficient lighting, or a flash, and was able to save the image in LR (thank goodness for RAW). It turned out to be one of the best images of the entire gallery. I could also recommend and on flash softbox, if you just really must use your flash on your camera. The off camera equipment you ordered will definitely help, too. I just really wouldn't use any of it, if you don't 100% need it. This is totally my own opinion... I am no pro.
