The full text of the spell reads, "Lets wizard move objects by the force of his mind. Objects may be picked up, thrown, etc. A wizard may do anything with TK that he could do if his own body were there. However, the object manipulated must be where he can see it. (Exception: A wizard with TK could use it to untie himself, even if he were in the dark or his hands were tied behind him.) For purposes of governing TK, the GM should assume that the wizard has one “invisible body” which he may place and use anywhere he can see or touch. It is possible to use a weapon with this spell – but any weapon controlled telekinetically is at an extra -4 DX. Cost: 2 ST per turn."

Note that objects may be picked up and thrown, etc. and that a wizard can do anything that he could do if his own body were there. The object manipulated must be where he can see it. Also, the GM should assume the wizard has one "invisible body" which he may place and use anywhere he can see or touch.

Again, the inference seems to be that the wizard could use his UC talents through his telekinesis as the object to be manipulated would be his opponent's head or perhaps his solar plexus.

The question of damage done by that TK use is going to be dependent on the ST of the wizard in question not an arbitrary decision as to what a wizard's ST should be.
