I took it to a guitar guy recommended to me by my guitar teacher and left it with him in his shop for a couple of hours. I explained what i wanted checking and because its been shipped etc, check neck alignment, relief and so on.
When I returned - turns out he loves the guitar. Only very small adjustments needed - the biggest one being action height which is very personal anyway. So after all else had been done, I played it, he adjusted it, i played it, he adjusted it some more until i was happy (a really nice, unrushed service with attention to detail).

Frets needed cleaning, and the nut was a bit tight he said, but everything else - very minor. So, I'm all set now.
Turns out he loves G&L and even went to the factor a few years back and had a look around. So I am double-chuffed to have found a nice guy, lots of knowledge, not into ripping off musicians (he is one himself), and a G&L enthusiast.
All in all, a good day.
One thing that struck me (and something we have talked about elsewhere here) is when he set the action quite low (in the first instance) - i could hardly play the guitar. I dont know if my hands have accommodated to the action over the last few weeks or what - but it needed to be increased a bit before i felt comfortable with it. It really is a 'feel' thing and there are no rules - in addition, i think my hands are changing as i become a better player - so i have more technique down now with which to explore different actions. It really is a learning curve....
