2001 Klein Attitude Comp upgrade questions

I have a mate with a 2001-ish Klein Attitude Comp that he is looking to refresh with a new fork, new wheels and new brakes. A number of questions have arisen:
1. Rear Disc mount
This bike has the old 22mm chainstay rear disc mount:
I've seen this referred to as a "Hayes mount" and an A2Z AD-PMR adapter should convert it to disc:
Has anybody tried this adapter?
More info under "Other" here: http://www.a2zcomponents.com/ada.htm
2. Fork choice
I think it would be true to the bike to go for something no-frills and light. He'd need something that wouldn't alter the bike's geometry (I'd guess something in the 80-100 mm travel range, but that is a guess).
The old fork is on the bike, what should he be measuring? Skewer to top of crown?
Informed opinions welcome!

Aha! Thanks for the clarification. I'll get back to you on that one...

That's a great help, thank you Nick. Link: http://www.bikeradar.com/forums/viewtop ... t=12563493
Oh, and I have discovered that a friend with an old Trek has used the A2Z bracket successfully with a Magura Marta front calliper.
see the disc brake sticky.

He's running a 160mm rotor with this set up, FYI. That's a nice solution because the A2Z site suggests that you will need a larger rotor (presumably using a rear calliper):
"Requires increasing rotor size 20 - 25mm. Please make sure your frame will accept a larger rotor prior to ordering."
Was it the adapter itself that fouled the frame? He's orderedone anyway, can always flog it again. I expect that he has a larger frame than your's, he's a tall bloke.
Thanks for the linkm I'll report back with developments!
Mark,
I've been thinking about this over the weekend and I realised that I'd failed to ask you the obvious question: what did you do next? Did you settle for V-brakes or did you find another way to fit a disk calliper to the rear of your Arttitude Comp?
