Yes, you can. You can also eat it at room temp, but if you'd prefer to serve it warm, bake it now, and then reheat it in a 200 F oven to serve.

You can, but you'll want to make sure you can reheat it just before serving so that the filling is warm, and the crumble crisps up again.
A&M are right, but consider to add a small scoop of ricotta on top when serving.
