You will not have to worry about humidity being to low and no need to worry about temps either. If you comfortable temp wise the shellac will be to.. In the 1700 they french polished and shellaced some very nice furniture you see in museums today and they did not have any AC or humidifiers and they did just fine. They did not however apply shellac when raining or very high humidity. Shellac does funny things when humity is high or moisture gets in the way. It will turn milky white and will have to be redone. Water on cured shellac will damage the finish in a very short time. You are doing it in the house so you should have no problems at all. Don't sit your drink glass or coffee on the cabinet or use the cabinet as a plant stand we know what happens to the finish then. We see it all the time. Waxing will help protect the finish. Yes after it as cured for a week or two you can put it togther and if you nick it then you can repair it with no problem. Same applies to the machine head when repairing the clear coat.
