Shouldn't that safe have been the creation of someone else? How else would he get into it to take her totem if he was not the one who created the safe? Or ... was that supposed to be real, i.e. not part of a dream?
When doing extractions, they get the architect to make a safe for the mark to put his secrets in, but there's no reason why Mal, being in control of her own shared dream, couldn't just make one for herself. I figured Cobb was able to work out how to get into it quite easily because he knew her so well (he was pretty much living inside her subconscious, after all), and/or because she wasn't trying to keep it away from him so much as trying to keep it out of her own sight (and thus out of mind), and so didn't bother trying to make it hard to break into.

But when he convinced her to kill herself so that she could wake up from limbo, she was still young, so they can't have grown old together.
I think that maybe they were able to change their appearance in a similar way to how Eames did; they allowed themselves to age normally until they grew old, but returned to their young forms at some point before waking up.

Personally, I'm quite happy to take the ending at face value; the inception was successful, he returned to RL and got to see his kids, the end. I think that the final shot was just intended as a bit of a tease and as a way to provoke ideas and discussion (mission accomplished). It's clearly meant to be open to interpretation, but I just can't buy the 'he's still dreaming' one. It feels completely wrong to me that, after having spent so much time arguing that the real world is unequivocally better than the dream world, Cobb would accept (or Nolan give us) a happy but artificial dream ending.
BTW, I came across this and thought it was pretty cool:
