There are some things you can do to help, shift some calories around, move some carbs from your non lifting days over to your lifting days around the lifting. But you don't have to complicate things more if you don't want to, but this can help with performance with your weight training.
We also can't evaluate your #2 without knowing what you are doing. It certainly is possible for 3x a week full body work outs to prevent muscle loss, I mean you could even do this every third day, which ends up being even less than three times a week, depending on what you are doing.
