One thing often ovelooked when setting up a studio is the need often to reduce light. So in addition to strobes and reflectors, be sure to budget in some black panels, flags, etc. for controlling reflections and other forms of stray light, and for increasing contrast when desired. Especially in a white-walled room, "subtractive lighting" is an important skill.
If you're looking at Paul C. Buff lights, be sure to consider the Einstein. For small product lighting the ability to dial down the power to low levels is handy, and for using multiple lights at different power settings for a portrait the "Constant Color" mode will be helpful.
Best wishes on your venture.
