The rear sprocket is held by the 5 or six nuts is all and you don't have to 
disassemble anything.  The stake nut on the front sprocket can be reused if 
you're careful during removal, and there are a couple of types out there.

Bend the stake nut on the front sprocket back carefully, have someone hold the 
rear brake while the bike is in gear and break that nut loose before removing 
the chain.  The DID press tool does a great job of peening the heads of the 
master link into place.

Use a small cut-off wheel on a Dremel to grind the head of a pin on the chain 
down before pushing it thru with a breaker tool to make it way easier to remove 
the chain.

I replaced with the DID-ZVM2 chain after successful use of the ZVM on my 
previous '99.  More strenght, less stretch, less adjustments and more miles. 
The last go round on my '03 I got the sprockets and the chain from 
http://motorcycleonlinestore.com/inc/sdetail/3102 as they had the best price (no 
affiliation, just a happy shopper).  The sell the chain to length so you don't 
have to cut it and include the master link.

FWIW, HIH...done this one a few times.
