Going to buy small studio equipment - WHAT DO I NEED??

I have a digital Canon SLR camera and am deciding what to get to achieve portraits similar to below. I have more of a video background and tried continuous lighting and didn't like the results too much. Planning on shooting in my home living room.

What exactly do I need for flash photography...(e.g. do I need 3 flashbulbs, an attachment to the camera?) Do I need to get stands?

I have a Lowel light kit for video pictured here. Can I use any of these:

You need to read.
Start by going here...
Multiple Strobes
and here...
Single Strobes

This will give you an idea of what you can do with different setups.
If you are on a tight budget and/or you want to be portable you may consider Speedlites on and/or off camera.
If you just want to stay in the living room a monolight or two or four might be best.

Start small and see what you need. READ READ READ is the biggest thing.

It wouldn't take much to reproduce the lighting in those pictures above if you know what you're doing.
If you don't know what you're doing you could spend thousands and never reproduce that lighting.
