I shoot with an E-500, got the kit that you are looking at. It is a FANTASTIC beginner DSLR, with the option to use it like a P/S until you are comfortable with the basics of DSLR photography. The menu system on that particular camera is super simple and easy to figure out, the buttons on the back are all easy to decipher and are very functional, again similar to using a decent quality p/s. I have had some great results with the basic package. Most of my fish shots are taken with an F2.0 50mm macro, but, my outdoor shots are all with the kit lenses and I am perfectly happy with the results in that aspect. Just remember that the 4/3 mount always has a 2x crop ratio, so, that 50mm that I use would be equivalent to a 100mm on a film camera, the crop ratio is much smaller on a Canon or Nikon. Olympus has a good selection of lenses, covering all of the basics easily, but, Zuiko lenses aren't cheap.
I have to be honest, I have had this camera for three years and I believe that I have progressed beyond the abilities of the camera now, I will be upgrading in the near future, not certain, but, likely to a Nikon, better feel to the camera than any of the Canon's that I have picked up.
That is my $0.02, hope that helps, at least a little.
