Congrats on the purchase. When you get glass that good for the first time, you'll never get lesser glass again! I think a prime is an excellent idea for an in-between lens. That's my setup actually: 10-22, 50mm f/1.4, 60mm f/2.8, and a 70-200. Works quite well for me, although I think I'm going to add the 17-55 f/2.8 (or possible the 24-70 f/2.8) to the lineup. I would suggest something similar for you, but good quality mid-range zoom lenses with constant apertures are expensive for any brand. I imagine a prime fits your budget better after dropping so much on the 70-200, so it would be a good choice. I love the 50mm focal length, but often I wish I had a wider prime (such as 35mm), so it's something to consider.

The shots look good. And for panning, a fast shutter speed isn't always necessary. If you use slower shutter speeds in the 1/30 - 1/100 range when panning, it gives that sense of swiftness by blurring the background and partially the subject, a different effect altogether than freezing the action.
