good candid despite the reasons you gave above..only real thing i would add is, watch for creases and lines around eyes and chins(not appl here) with women and try to keep hair out of eyes unless done so specifically.
Other than, get going. check the help threads for lighting kit links as i'm sure someone else had the same thoughts as you for getting into studio lights
Get buying, get shooting and get posting!
