If i could spend your money I would do the following:
Dura ace 7700 down tubes
dura ace stem
dura ace brake levers
white selle italia slr saddle
White fizik perforated bar tape
silver white industries hubs 24h/20h
50+mm carbon rims (hate away

)
veloflex tubulars w/ a tan sidewall
But if it were your $$'s ?
I'd go cheap and have fun: All City polished chrome crank $112, Set of Formula/Sun CR18's $119, rear cog $25 and sell the existing wheel set crank and derailuers and buy a used Brooks , 3 feet of link chain and a lock....with the pocket change I'd get a 6er of PBR's and a pack of Lucky Strikes and head for Coney Island.....it's summer man!
