I just built a long hive. Had I started with a long hive, I would probably have gone with deep frames instead of all medium. I plan on managing it like a regular 3 box hive and stacking supers in the rear of the hive if they make me lots of honey. When expanding the broodnest, you want to add empty frames in to the broodnest. For a vertical hive, you do the same, but expand in to new boxes starting with the center.
I let the bees draw their own comb. It's cheaper and less work assembling frames. They sometimes build comb that isn't straight on the frame, but it's easily corrected if caught early. It's also less frequent once you have already drawn frames to use as guides. They'll make cells the size that they need and it's interesting to see different cell sizes on the same frame.
Wiring frames is helpful if you plan on using a radial extractor; the comb is less likely to collapse. I crush & strain and the few wired frames I had were really annoying in the process.
