Actually these are the be best hubs ever made. Superior cup and cone implementation, highest quality cups, cones and balls, and a light titanium freehub. Every part on these hubs (including the cups) can be replaced easily with readily available parts. These hubs should last a lifetime if not completely abused and neglected.
Anyway, back to the OP: very nice frame. The 7403 brakes are the best road rim brakes ever made. The crankset is outstanding as well. This is well worth building up.
Comment: your downtube shifters (7 speed 7402) are not compatible with your rear 7700 (9-speed era) derailleur. The cable pull is mismatched, and it will not index shift over any cog spacing that I am aware of. Keep in mind that most Shimano 740X series stuff is completely off onto a world of its own in terms of incompatibility and being long orphaned. Particularly 740X series cassette hubs. Do NOT get drawn into taking any of this stuff, even if it is free.
