Went through the exact same questions and rationale myself. I started from scratch with EF series lenses with new 10D, and ended up with 3 lenses. Below, and why:
24-70L - Most used walkaround lens, exclusive indoor lens, good portrait lens at 50-70mm and stopped down. My 10D has this lens on it 90% of the time, with a 550EX.
70-200 f/2.8L (non-IS). Outdoor versatility, general outdoor use. You can catch almost anything outdoors with this, with the exception of distant sports. If you take High School sports pics, 200mm is about right, you can put plenty in the frame, and crop what you want. Any more is almost too much if you're close to the action. Very versatile. I just now wish that I had bought the IS, after finding how valuable it is in my 3rd lens,
300mm f/2.8L IS - Reach out and touch someone. Yes, it's expensive, but it's beautiful. I debated the f/4 vs. the f/2.8, and decided that I regretted being cheap with the 70-200 non-IS, so I wasn't going to be cheap on the 300. It's fast as hell. Used it last night shooting a baseball game, and I positioned myself along the 1st base line (but back a bit!), so that I could catch the batter's box, first base and second base if I whirled the head around. Perfect framing for the batter's box, perfect framing for second base, WAAAY too close for much of a picture at first base, but if a man's on first, and the pitcher tries a pick-off move, it's perfect for moving to the bag, and catching the tag or the runner's body/face as he's trying to get back to the first base bag. The 10D focuses FAST in AF when going from batter's box to first, or to second. FAST. Did I say FAST?
I used to shoot with a Minolta D7. It could never have done what the 10D does. I couldn't be happier with my choices, with the exception I wish I had sprung for the IS with the 70-200, to make it more versatile walking around. The IS really makes a difference with the 300mm.

I have some money to blow over the next few months on lenses and
are pondering which ones to buy. But want to get the most bang for
the buck. So no 6000.00 ones. If you had to start from scratch
what would you buy to cover as much as possible with 3-5 lenses.
And if you have time why would you buy it. Maybe if you could rank
as most important downward.
I currently have a 10D and a 70-200 IS, 1.4x, and soon a wide
angle. What would you choose? Which one do you enjoy/use the
most.
Thanks, this will help me as well as others who have a 10D and are
pondering which lens to buy.
