Congratulations on your beautiful bike! I just bought a Soma San Marcos 51cm for my girlfriend as a christmas gift, so I have hands-on experience on this frame.
*Brake reach*: What size is your San Marcos frame? The brake reach is specific to the size, and Tiagra sidepulls may, or may not fit. 47, 51cm use 650B wheels and long reach brakes (55-73mm) Larger sizes use 700C wheels and standard reach brakes (47-57mm) EXCEPT: the newest production frames, 2013 on, use long reach brakes on all sizes. I don't know how to tell besides measuring. (I did speak to someone at Soma, though, and they said the newest run of frames also has Riv-style mid-blade fork eyelets for a mini rack. I don't know if this corresponds to the brake reach change). *Dropout spacing*: I've successfully spread the dropouts on two older steel frames, by hand, using the Sheldon Brown 2x4 method. Crude, but it works. (I should probably take both frames down to the bike co-op to double check alignment, but they both measure up straight and shift properly). HOWEVER: The San Marcos has beautiful lugged rear dropouts (seriously, I haven't seen the like), not skinny old-style ones. This may make it harder to re-align the dropout if you managed to bend it out of whack when cold setting. THAT SAID: You can probably just cram a 135mm wheel in there. Try it! You can spread the dropouts slightly by hand in order to facilitate. You won't bend them far enough to deform/cold-set them; you'd have to spread them much wider to do that, as Ron Mc stated above.
