I would first place the desk and chair so I can walk in, sit and stand up again without hitting my head (done that too many times in my craft/storage room). A book shelf for stash/book can be placed up against the back of the desk or covered with a curtain if you don't want to look at it. If it's tall you could use that vertical space to your advantage. There's an odd space just inside the door my DH put up pegboard and hooks for me to hang rulers, etc. on and I put the mats underneath. Might have to take pictures and let you see my mess tomorrow.
