Powertap 2.4 freehubs (wireless 2008 model)

I recently landed a used wheel with Powertap 2.4 wireless hub, 2008 model, with a campy freehub.

I run a shimano 9-speed setup, and I have a couple of questions...

1. If I swap the freehub to a shimano-compatible one, does the wheel need to be re-dished?

2. If I just get a Miche 9-speed cassette and Jtek shiftmate, would I have any problems using the wheel with a shimano 9-speed rear derailleur, chain and shifters?

3. Does anyone know if this is Ant+ compatible, or do I need the hub updater if I wanted to use it with newer garmin computers?

4. Powertaps are not sold where I live (South Korea), so I would have to send the wheel overseas for service. What kind of issues should I watch out for if I wanted to avoid this hassle?

Here's a picture of the wheel/hub in question: http://imgur.com/grOzd

Yes.

The 2.4 is not ANT compatible. The 2.4+ is although some 2.4 (I bought one) hubs got updated without receiving a new end cap.

4. Powertaps are not sold where I live (South Korea), so I would have to send the wheel overseas for service. What kind of issues should I watch out for if I wanted to avoid this hassle?
Verify that the offset is 512 +/- 8 or +/-12 (internet reports vary and the manual gives "about 512" as the specification) inch-pounds because an out-of-spec zero suggests issues which may include the hub being inaccurate due to problems with the slope or linearity, out-of-warranty rebuilds are $350 from Saris, and starting in Korea you'd want to remove the hub from the wheel before shipping.
