Yes, you can. The rendered maps do this for example.

No, you don't need to. But bear in mind that under BY-SA the users of
your version of the data will be free to copy it for use outside of
the application or to give a copy of it to their friends for free.

"Copyright OpenStreetMap and contributors."

The CC website explains various ways of attributing work here:

OSM is under BY-SA 2.0 rather than 3.0, but it's easy enough to change
any text or URLs from the above page to reflect this.
