do y'all know anyplace where I can learn the basics of strobe lighting?
What Matt says.
does it work with umbrellas (this is a total newbie question, I'm sure)?
Yes, and through them too. And with softboxes, snoots, barndoors, gels, pola gels, etc. etc.
However, since I don't have a fixed studio and (because I) spend more than 50% of my time on location, for mobility, I have a 'portable studio'. It basically consists of 3 wireless 5600D flashguns on tripods, a 3' and a 4' silver/white reflector. Gives me plenty 'oomph' and endlessly variable possibilities, including faking 'softboxes' and balancing shadows. Easily fits a medium-sized suitcase.
When working with people as subjects I mostly use the camera unsupported. Flash freezes motion anyway, and it keeps me much 'free-er' to move around, direct the scene, try different viewpoints and angles, and/or adjust the light.
I submit a 'portable studio' like mine is much more flexible than a fixed studio flash set and is therefore used much more often.
The downside is that you have no modelling light. But hey! this is the digital age so you just do a test shot and
look whether you like the light setup as is.
