Jim Cooper as well as many others have some great ideas for building homemade light tents and light booths out of PVC pipes and some sort of diffusion material. Look at some of the "how-to" pictures and you'll understand what I'm talking about. The tents and booths produce a soft, even quality of light without harsh shadows.
Just starting out, I don't think it gets any easier than a bright, overcast day. They don't call it "nature's softbox" for nothing.
Continous light sources like floodlights give you more control on where the light is coming from. It also allows you to see what the light does to your subject (ie where the highlights and shadows are) as you move the lights around the scene.
Get to know what color balance settings work best for the type of bulbs you are using. Better still is to learn how to take a custom white balance reading. I think it's far easier to make the proper setting in-camera instead of relying on Photoshop (or some other program) to try and fix a bad color cast. Photoshop only goes so far.
It's not like you're burning through rolls and rolls of film...LOL...It's digital...take lots of photos but TAKE GOOD NOTES. A little lighting diagram, exposure/white balance settings, etc. This way, when you get a photo you're happy with, you can look at the notes and be able to duplicate the setup.
Most importantly, don't get discouraged.
