I just finished picking parts out for a similar build. Custom 650b frame, more money than I should have spent, etc, etc. But mine is more road/rando (light front load) than touring.
Chorus 11 mechs and shifters, White Industries crank (46-32), Paul touring cantis, and I'm building the wheels today ... white industries T11 to Pacenti SL23 rims.
Oh, and congratulations! That is a most excellent gift.
