Shoe trees are good options there, of course. You could also put it with some cash and pick up some AEs.
Don't mess with the pants - they have an odd cut, and the seams don't hold up at all.
In terms of other stuff you can get there at decent quality, I actually don't mind their shirts. I mostly buy BB non-iron shirts, but their non-iron shirts aren't bad in the tailored fit. I still have quite a few hanging around my closet that are among my favorites (small-timer that I am).
I have gone from a closet full of JAB stuff to one with shirts and shoe trees only from there, just to give some perspective.
