As far as I know everything on your checklist can be fixed, if you haven't fixed it already.
Maps can be downloaded from android market or market.android.com.
My contact-sync is working flawlessly with facebook. Are you sure you have automatic sync turned on? Maybe try reinstalling the app.

And just so you know, people tend to be more helpful if you write because you need help, not because you're complaining.
Words of advice, my young padawan.
