For the crayon,you can get a magic eraser from Mr Clean,and it works great on stuff like that and scuff marks too. It looks like a spong, and you can dampen it, then scrub at the offending marks.
For the sticker? I recommen some stuff literally called 'goo gone'. It comes in a small clean bottle and has very easy directions.It specializes in removing sticky material like that.
