you should be able to get holes pre-drilled for the Type A bridges, but it is an added cost to do so last time I checked. The Vintage bent plate bridges are a direct swap out for the standard 5-hole bridge pattern, so this can be done at no added expense. I've never inquired on the other Hipshot models, as I usually don't use them on my builds.
for the tuning keys ... it's a little bit more difficult. exactly where do you want them? I rotate mine just a pinch off perpendicular, so a pre-drill for the screw would not do me good. pre-drills would only work for the Fender style headstocks, as the others leave too much room for subjective rotation to make everybody happy.
all the best,
