Ok, you've got a lot here, the second to last picture, the large nipple is the brake booster vacuum connection. The last picture I believe you are asking about the brass part, is where the coolant temp sensor that controls the dash gauge goes. You do not need the air pump if you don't want it, it was there to pump fresh air into the exhaust to prolong the life of the catalytic converter. If you remove it you can have the SES light tuned out when you have the PCM tuned.
Noted! I found someone that sells a VSS kit for my car.I don't know about the painless harness and computer, but the factory computer needs the vss signal for computing air/fuel ratio, as well as automatic trans function.
