#1- As long as the key transponder chip, the ECU and the EWS module located behind the glove compartment are all from the same vehicle, you won't need to have the EWS aligned. Just don't forget to swap the chip out of the keys and swap the EWS module behind the glove compartment. DON'T swap the antena ring around the ignition or the EWS reciever in the driver's side legwell. Use your old ones.
#2- You should still use the secondary air pump. Many of us who have done the swap have relocated our battery to the cargo area. This helps maintain the factory weight balance of the vehicle. Since you'll have a donor vehicle, you might as well relocate your battery since you'll have all of the hardware, positive distribution block and long positive cable. The secondary air pump is a vital part of an OBDII emissions system, why not install it instead of having an extra wire hanging off of your harness and and a CEL? The battery tray in the engine compartment doubles as a bracket for the secondary air pump on 6cyl models.
#3- You're going to need a boot for a model that did not come with ASC. You might also need to remove the ASC relay and/or figure out a way to bypass it.
