If what you want is flat lighting to just show your product, then a light tent is your best bet. Set it up according to the instructions and then set the white balance on your camera to match the light source (strobe, tungsten, flourescent, etc). They cost one or two hundred dollars. Cheap, but effective.
If you want some shadowing to show texture or depth, you'll want a system that'll allow differing intensities of light (image 8.) Same is true if you want a light base but a darker background (image 6.) You'd use a background that's different from the base for the same, or for intensifying, the effect (images 10 and 11.)
Mood is important: Light and airy (image 7), dark and mysterious (image 1) or somewhere in between (image 4.) Or - and this is done only with great care - reversing the mood (image 9.)
But the best way to learn about photographing your products is to leaf through magazines and look for ads or articles of products similar to yours and study the pictures.
Read a book or magazine article (or two) on photographic lighting. I recommend
The Studio Photographer's Lighting Bible by Calvey Taylor-Haw. (Amazon, camera store.) He covers lighting for everything from food to small products to refrigerators to pets. Lots of photos and lighting diagrams.
I'm including a few practice shots I've taken in my tiny studio, with a quick description of the lighting I used for each:

If you have any technical questions or questions regarding any of my pictures, feel free to ask.
I hope this helps. If it does, you're welcome.
