I have 105 RD, FD, crankarm and 39t/42t chainrings, just need 8 speed indexed DT shifters and clamp. I have some SR randoneer bars and Dia-comp aero brake levers that I want to put on along with the setup mentioned. Oh yeah, I need to replace the crappy seat and post.
and I want this setup

And BTW, 27 inch wheels are not obsolete, they have class and and also over here you can find anything from 24 1 3/8 to 28 1 3/4(25X635)
