What to bring in Vulcanus?

so energy wise, should i bring nuclear reactors and such or i can use resources from there? I don't intend to do a megabase, right now Nauvis is about 90GW, half nuclear half solar+coal.

miners, belts, inserters, any chemical plants or oil production needed?

Is it better to bring any plants from Nauvis instead making it there? I want to avoid back and forth as much as possible.
