Point 1 is correct, the selling of bonds by China will have the effect that their prices will drop. That's the law of supply and demand in action.
Point 2 will probably also happen; but only up to a limited amount, because:
Point 3, and the others, won't happen. There will not flow more money towards the USD. What happens now is the opposite; China is selling USD's. Again because of the law of supply and demand, this will lead to a drop of the USD rate.
If the drop will be too much for the FED's taste they will increase the interest rate (point 2), but only so much that the depreciation will stop.
