1-Go to File\addnew track\ select stereo\Master fader.
2-You can add a stereo compressor and Limiter to your new master fader.
3-http://www.bombfactory.com/ You can download a demo and you can buy on line too. If you purchased 001 you should have gotten D-Verb included. If you are using PTLE free then I guess you can get it from Digidesign's on-line store.
4- I'm using the Events 8" active monitors. They give you a good flat response. Check them out here.
