Let's focus on the simplest question and work through them.
First, you need to tell us the clock frequency.
Now, 'sources' actually means 'time-averaged noise' or 'the noise averaged over one clock cycle' (I don't know why they call it 'sources'). Since this is a track and hold, I would expect it to have roughly a sin(x)/x shape. The shape will be corrupted somewhat because this is not an ideal system (there is some feed thru, the switches do not act instantaneously, etc.). So the output noise seems reasonable to me at first glance. Why does it not seem reasonable to you?
