2: Generally speaking, yes. All depends on how well the server is monitored.
3: Yes, as the admin tool they use will show you in electro 1 minute, and NWAF the next. It lags, BUT it doesn't lag to the point of you running 20 minutes THEN it updates.
4: Not quite sure on this one, but I am fairly positive it tells who spawned it, etc.
