Help me plan: My first intake swap ... EVER.

Dont rush.
Silicone sealant wont skin over in the couple minutes it takes to place the mannifold.

It wont be a problem if it skins anyway.
On diff covers i apply silicone and take a break to let it skin a little. Never leaks. Done this since the beginning of my auto repair days.
I set the manifold, torque, and bolt on the goodies. I let it set up overnight. Good to go the next day. Silicone needs air to cure. I also leave the PCV and oil fill cap off. I have seen guys at dealerships slap a rear end cover on, fill it with lube and off for a test drive. Sorry, I don't do it that way.
