That Gibson is an amazing gift, and one that your son will treasure for a lifetime. I have had my 1971 Les Paul Sunburst Standard since 1978 and about a decade ago my wife dropped it while she was moving it, breaking the headstock which is at the top of the neck. They are very fragile there, and most vintage models out there on the market have been damaged in that same spot. They can be fixed by very carefully gluing them by the hands of a professional Luthier and will play just as well as they did prior to being broken, but just tell him to be careful with it.
As for my regular playing and practicing amp, I have a Fender Champion 100 that I use with my Gibson, my Strats and acoustics. The most important thing is to practice and to develop a good tone, then throw electronics at it.
