You can easily get 36 spoke wheels, just have them hand built (which is much better than factory any day of the week) - and not all that much more expensive. I believe Harris Cyclery in MA will build em, and I know a great place called Bikeworks in NYC (they have a website) which built my 36 spoke Mavic Open sports with Phil Wood hubs and double butted ss spokes pretty cheaply. They've never had to be trued, ever. The seatpost= might want to turn the bike upside down, after dousing it in WD40 for a couple hours, then take a hairdryer and heat the seatube. When it's nice and warm rubber mallet the old seat and post down out of the frame. Gravity seems to work wonders for this, don't know why.
