The Flight Factor 757 is pretty good. Not quite like PMDG but up there. However, my favorites to fly are the FlyJSim 737-200 and 727-200. They surpass anything you can find in FSX for those aircraft, and that's part of the reason I fly more in X-plane because I really like the older stuff. If you like the modern stuff, then it's probably worth waiting for the PMDG stuff to come over. And IXEG is working on a 737-300 that looks incredible. As far as helicopters, X-plane has some really nice ones. IMO, much better than dodosim. I fly the Dreamfoil R22, 206 and 407; all amazing!

It's an optional service provided by ATC for VFR aircraft. They can give you traffic alerts while enroute. You simply call the controller and request flight following. They will give you a squawk code and identify you on radar. But since your VFR, your still have the primary responsibility of maintaining separation, but it helps if your flying in some busy airspace.
