TeleFragger, you don't specify what format you are shooting in, jpeg or Raw?
One of the big strengths in the Canon software as well as Lightroom is that they both have Raw processors that each are in their own way quite nice. Lightroom, though, also has the powerful organzizational tools built into the integrated interface.
If shooting jpeg, you may want to look initially at using Photoshop Elements, at least at home, because it has a lot of great tools that neither Lightroom or DPP have for editing photos. It will be a good app to have even if you go on to use the Canon software or Lightroom or both. In fact, having all three apps at the ready can be a real plus, especially if you get into Raw shooting.
As far as your basic workflow, of course it starts with having a good efficient way of downloading and saving your images in a useful format. What you are doing is fine, although you can use Lightroom to automatically download, name and Import images if you get a card reader.
But without a card reader the EOS Utilities is probably the best approach, although I believe ZoomBrowser will also connect with your camera as well as a card reader. I'm not sure about all ZoomBrowser can do, but I see it has options for communicating with the camera or card reader.
