I use this exact set-up (36" dia. umbrella) as much as I can for portrait, I set the flash on auto but set the camera settings manually. 24 mm setting is what I use always on the 550EX, you want to diffuse the light when you use the umbrella (or "brolle" for Malcolm), don't you? I suspect the 105mm setting may make the light more harsh again. I do find the umbrella soaks up a lot of light, the one I use does allow some light to transmit through the material which does not help to use the light 100% efficiently. Even with the light output reduction, I do like the effect the set up provides which is very pleasant.
