Why oh why would you change what is a very nice bit of history, if you sell off parts and replace them, its not the same story / bike
AFAIK, the spokes on the wheels aren't replaceable, so wouldn't want to risk damaging them... won't be selling them, they'll be kept for the occasional dry & sunny 'posers' pootle 
The SRAM shifters and mech, well I'm not a huge fan of them, as has been pointed out they do clash with the rest of the bike, plus they appear to be worth quite a bit of dosh (if I can find the right buyer) so they'll probably go to fund some nice XTR bits (maybe retro, maybe new...)
Cook Brothers cranks and rings, well I like these as well, but they're a bit too nice (to me) for general use, so they'll be kept but probably not ridden.
