If it's your first grow, I would strongly recommend using CFL lights. They are cheap, and reliable, and they have low heat output too. This means that you don't have to spend hundreds on a huge HPS set up, with fans, cooling tubes, whatnot...
Soil would be a good growing medium, as it is probably one which requires the least maintenance. Get some basic nutrients for vegging (high nitrogen), and flowering (high phosphorus, and potassium).
Other than that, you should be fine. Auto-Flowering cannabis strains are usually extremely resistant, and forgiving. So i think you should be fine.
