Well rounded bunch of tips!
As part of your planning ahead: Try getting the chickens intended for slaughter after dark the night before when they are asleep on the roost and put them in a cage or pen with water but no food for the night. It's worth not running around like crazy trying to catch them when you already have a bunch of work ahead in butchering them.
For scalding, time is going to vary a little from chicken to chicken. Some can take up to a minute. Dunk for 30 seconds and then lift just enough to pull at a primary feather on the wing. If it comes out easily, then they are done. If not, keep them in there for 10 more seconds and try again. Just keep doing 10 second increments until that feather comes out easy!
