2. can I fit the 10 speed group on the 520?

1. As long as you don't get something with French or Italian threaded parts, you should be fine for most everything
2. You will need to cold set the rear triangle to 130 mm spacing. Sheldon has instructions
3. That's cool. If it works for you over the 610, that's what matters most (Though I'll still dispose of that 610 for you
...I'm only 3-3.5 hours away) Your limiting factors on your 520, as already mentioned, will likely be your cantilever brakes. You might be okay, but you'll have to measure the reach and how much adjustment you have, both vertical and horizontal. It's easier to make the switch down to 700C with single or double pivot brakes, as they mount above the tire and not on a post next to it.
Other than bike fit, you mention gearing...which would be moot if you are changing that. If you can get ahold of a 700c wheel, try mounting it to see if you can adjust your brake pads enough to work. I would mount both front and back, just to be sure.
