I've tried looking at other forums for the solution of this problem, but so far I'm not having any luck. Maybe you can help.

Currently I have this Eric Clapton Signature Model Martin Guitar. I love the thing to death, but there is one problem that I have with regard to the string height(I'm not sure if it's called action or not). So the string height is giving me problems and I'd like to lower it for the ease and efficiency of playing. Some sites have mentioned vague generalities, but I have yet to come to a worthy conclusion.

Any websites or recommendations would be appreciated. Also as this guitar is pretty nice and expensive and I'm not interested in doing anything myself that could potentially damage it. Should I just bring it to a professional??
