Note that my paramater order was designed to be done as lazily as possible too. Using your example, say I had the url http://foobar.com/results-2000-01-25-final.html and I wanted to get 2000-01-25 through 2000-01-28. My sequence of operations would go something like so.

First I would type the command:

wget `urlrange `

Then paste the url:

wget `urlrange http://foobar.com/results-2000-01-25-final.html`

And finally all I have to do is move my cursor over to the 25, add a space before and after, and put the last digit of my range. My result would be something like:

wget `urlrange http://foobar.com/results-2000-01- 25 28 -final.html`

Which, I would say, is about as lazy as it can get (in terms of number of keystrokes). But... to each his own, I suppose. Your interface seems to work fine for you.
