Stars Wars bedroom, here we come!

My 7 year old son is crazy about two things - Star Wars and Lego.  Lucky for him, there is Star Wars Lego.  I have been wanting to put together his room forever.  When we moved back from Yemen 2 1/2 years ago, I kind of just used what we had.  It was cute, but pretty generic.  Because our little house has only 3 bedrooms, my daughter's room becomes the guest room when we have company.  She ends up in her brothers room on the floor in a sleeping bag.  We finally got the bunk bed that we wanted (thanks to Grandma and Grandpa). 

The plan is to do a full-on Star Wars themed room.  Now we don't do the new Clone Wars stuff, we only like the original movies.  But, it's hard to find retro Star Wars fabric.  The only store that carries it is Potterybarn Kids of course.  So, I splurged and bought the twin duvet cover.  This is my plan, I'm going to take apart the duvet and make it into two duvets (because it's a bunk bed and I need two of everything).  I'm just too cheap, and does the duvet really have to have Star Wars on the back as well as the front?

These are the fabrics I'm considering for the back of the duvet.  They are all very reasonably priced and they are 60 inches wide (which is just about wide enough for a twin duvet).  Which one do you like? Decisions, decisions.

And then there is the wall color.  The room is a sage greenish color right now.  I'm looking at these warm grey colors from Benjamin Moore.  I'd like to get started on it this weekend.  Please share your thoughts and opinions.

Oh, I had taken some "before" pictures of the room.  And then somehow during a garage sale, I gave my SD (memory) card away (long story, not so proud).  The garage sale was a waste of time.  We of course made no money.  Garage sales really are a waste of time.  Oh well, we did get rid of my son's old twin bed and it's not in the garage collecting dust at least.
