The action on my upper frets is considerably higher than the lower frets. Firstly, am I right in assuming that this is a truss-rod adjustment thing and if so, do I turn clockwise or anti-clockwise (looking from the headstock looking towards the body)? Help would be much appreciated here...
If the neck isn't bent the truss rod is OK. Look down the neck or use a straight edge to see if is. Did you try adjust the action (string height)? If the strings don't buzz, try dropping the height some.
