You'll need one from the plenum to the fuel pressure regulator, one from the plenum to the wastegate... That's pretty much it. Block pretty much everything else off. Maybe leave the PCV valve in place and the hose going to the intake manifold, but you can also run it to a catch can if you want.
The big ones coming from the valve cover can usually just go to a catch can. You can run one from the air filter box (before the turbo inlet) to the catch can to keep pulling vacuum in the valve cover, but this will also pull oil vapor into the inlet. It only works if you have a sealed catch can though.

Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.
