I don't see anything wrong with those numbers at all. You could shock the pool again if you wanted to Friday right before you leave, take the chlorine up to 15 ppm but otherwise that's about as good as it gets

You could put some trichlor pucks in a floater if you wanted to and leave them in the pool (I would tether the floater so it doesn't float over next to your liner and bleach it) so that there is some continuous chlorine feed in the pool, or you might consider having somebody come in and dump a gallon of bleach in the pool every couple of days...
