Quilt rack: clean up to finish

My mom has a hanging quilt rack that is used to display a quilt that her dad, my grandpa built.  I dont think there was every any finish applied and it was left rather rough. Mom has never hung it in her house and she asked me to clean it up and finish it so that she could hang the quilt rack in her kitchen.

Here is how the piece looked after I took it down from the rafters in dads garage and had went over it quickly with the random orbit sander.

 I trimmed the rail off the front to make it easier to finish. Since it looked like all the joints were glued I took all the screws out to keep from running the sander across them.  While trying to sand/plane a chip out of the front of the shelf I knocked the ends off, apparently the glue wasn't as strong as I thought it was.  This will be easy to re-attach and will actually make it easier to sand all the parts. I was thinking about plugging all the screw holes after I re-assemble it.  I will staining it to make it compliment mom's kitchen cabinets.
