Can you TK a figure to elevated terrain, if the target square is in range and in line of sight? And from elevated to the ground?

Yes, as long as the TKer has line of fire to the target square you can move another character to a different elevation.

I love moving one of my opponent's big slow close combat pieces up to a roof where it'll take him 6 turns to get back down an into the battle (or at least force him to waste two turns taxiing him.)
