1. The qwerty keyboard is built in both hardware and on screen just click on input methods when writing a message and it will come up.
2. There should be android market icon in your menu which looks like a green robot, click on that and you'll end up on android market. You need internet connection for that. http://www.android.com/market/#app=com.com2us.HG
3. These are the colours available Black/Lime/Red/White
4. Facebook should be built in your phone but yeh they are both listed on android market.
5. Facebook doesn't use much but watching youtube movies will take a lot of bandwidth, I suggest to use your wifi connection instead of network connection.
