Hi Lisa:
welcome. What helped me immensely with lighting was having stobes with modeling lights that can be turned on and aimed prior to taking the actual shot. This helps to see where the light falls on your subject and was a good training aid for me. Most decent strobe manufacturers (Elinchrom, Calumet, Alien Bees) incorporate this feature in their products.
Lighting is one element of photography that can make your head spin when the research phase begins. There are so many high-quality options out there. For whatever reasons, I chose to go with Elinchrom. They work fine and produce tremendous results when used properly, as will products from other manufacturers.
Best thing to do is determine needs, set budget, then buy the best quality gear you can afford. After that, learn how to use it and take care of it and the gear will provide years of quality service for you.
