I don't think that you need to worry too much about the P401. It basically means that you are spewing emissions into our atmosphere at a higher rate than normal. Get it fixed at your convenience.
I believe EVR means EGR
Vacuum Regulator. It's really a solenoid valve (open or closed) that regulates vacuum to EGR valve.
While I would generally agree with the above statement, in view of your destination I would say get it fixed sooner rather than later.
p.s. Seriously, I think first step should be reset PCM and see if or when CEL next appears.
p.p.s. Why don't you delete 6:04pm post and clean up the board.
