please, please, please, don't machine quilt it!! It would be like putting a modern fabric on as a border. It is beautiful and deserves hand quilting - doesn't need to be fancy, let the pattern on the top shine through.
I have hand quilted several antique tops, it is so nice when they are finished and can be used as quilts. I HATE when people make tablecloths out of them (you see that in magazines a lot.)
