So, my studio/workshop got robbed, and I'm starting over.

Does anyone have any recommendations on studio lighting for portraiture, or suggestions what to read?

I'd like to do studio portraiture starting in 35mm and moving to 4x5 when finances allow, but I really have no studio lighting experience.I took photog. at uni but we never really covered artificial light in a practical way my hero is Karsh and I'd like to make my current living room into a portrait studio and use my bathroom as my darkroom which worked before. I'm lucky I live alone.

Thanks for your time and responses,
