Trim it, only when it is neccesary.
Well, it depends on how short you cut it and how long you want it to grow.
Sometimes, people's hair grows faster when they get it cut more often. But, no it is not necessary to cut your hair to get it to grow, but it is healthier for your hair to get it cut once in a while.
No...layering the hair does not make it grow faster. Nothing, as far as styling, cutting etc makes the hair grow faster. If you are trying to let your hair grow out of a certain cut, say for instance, you want to top and back to grow out, you should cut the front more often and vice versa. This will give the hair that is shorter the "chance" to catch up the to the longer hair.

Hair colour deposits into the hair follicle, it will grow out in time. It depends on how long you want you hair to be.
