I have some questions/suggestions before buying.

1. On my first flight I got a early "descend to xxx at pilot discretion" and then further descend after I started down, but on my second flight I got descend clearance (without pilots discretion) shortly after reaching cruise level. Long before my actual TOD. Wondering why this happened?
2. ATC gave me speed reductions on the approach for both my flights, on the first flight I was number 2 behind a B200 and ATC separated us perfectly. On the second flight ATC also gave me speed reductions, but this time I was first in a line of several aircraft. Are there speed reductions on every flight regardless of traffic? Do PF3 actually separate me from other traffic or was I just lucky on my first flight?
In most of the places I've flown to in RL, speed is normally decided by the pilot if traffic is not a factor.
3. Would be cool with a random chance of being assigned a STAR vs. getting vectored.
4. I only have one monitor and run FSX in fullscreen. Is there some way to get a display that show frequencies and communication options like default ATC or RC4? I'm having a hard time remembering what the different hotkeys do, and have to ALT-TAB a lot to check the user guide.
5. When being vectored on my second flight, the pilot sometimes responded incorrectly. ATC gave me an instruction to "turn right HDG 235" and when I responded my pilot read back "turn left HDG 225". Happened several times, but not every time.
6. Also got a very late approach clearance on the same flight. I was on a good intercept heading for a long time, and didn't get the approach clearance until the localizer was alive, which led me to overshoot the localizer.
