Also: the moon does rotate. You only see one side because it rotates at the right speed to always turn the same side towards earth. I actually don't think rotation matters.
Ok: here is how you would calculate it:
Calculate the speed required to orbit earth at the distance of the moon (don't recall that formula, something M1+M2/r^2 but that has been a while)
Find the speed the moon is actually orbiting at.
Find the minimun delta V to push the moon below that required speed. (Vm-Vr)
F=M*V
There is the force you need to do it

Is it possible that an impact of an object into the moon could change its trajectory just enough to send it on a collision course with earth?
How fragile is the moons orbit?

The orbit of the moon is actually getting larger.
Sure it's possible that a MASSIVE impact could change the orbit of the moon but any object large enough to change that orbit would also most likely wipe out all life on earth anyway.
The moon has taken many impacts in the past, thus the craters so I wouldn't worry too much.
Consider this analogy:
Try playing pool (billiards) by rolling a bb pellet at the pool balls.

What about the moons core?
PS: The moon takes 27 days to revolve and.... you guessed it, 27 days to rotate as well.

And it just so happens that the visual diameter of the moon from the earth is exactly equal to the visual diameter of the sun from the earth. Ie: Lunar and Solar eclipses.
How come there are craters all over the moon, and not the earth?

Yea, that's why we have a 'dark side' on the Moon.
