Bill,
I am a Canon person and a semi-pro photographer. The Rebel cannot use all of your lenses, as I understand it. I have simlar lenses and I bought the D-10. You will be able to almost use it as your did your EOS cameras with little learning curve. The D-20 is just out and it is a higher megapixel, which for most things, you probably DON'T need. There are some good buys on the D-10 since the D-20 is out this month.
You can just pop your Compact Flash card in the photosmart printer. Or I bought a card reader - they are $25.00 approximate and then you use it like a floppy disk and can drag and drop the photos.
If you are looking for a more compact camera, you'd need to forgo the SLR aspect but I also have a G2 Powershot Pro and it takes great images for travelling.
You can sell or trade your equipment through KEH Cameras in Atlanta (KEH.com) There is a good market for used stuff in good condition. I tend to buy from B & H Photo, Calumet or my local small store.
