The only thing I will add to what has been suggested already is no matter what you do, try to keep the logo design simple. Simple in terms of shape and colors. Some of the world's most recognizable logos only have around 3 different primary colors in them. Of course, it needs to be eyecatching and identifiable as well, but the more simple the design, the faster people will recognize it, and also the easier it will be for you to reproduce it where you need it. A logo will come in very handy for watermarking your products, and in some cases, this will require a transparent gif or PNG version of the file.
