you should not have to add any vacuum lines.
make sure you use all of the intake lines cuz if you leave one off you car will surge. if you have extra lines just plug them.
there should not be a second o2 sensor but dont hold me to it!
as far as the MAP Sensor goes you have 2 choices.
you can either hook up the map on the intake and leave the one on the firewall alone or you can buy a MAP sensor block plate (www.kmsperformance.com and they have them on ebay) and use the one on the firewall

that is how mine is hooked up in my accord and it all should be the same!
good luck
