Answer 1

Pretty simple.

As stated previously just remove the screws.

This particular device can be purchased at Lowes or HD.

Not a whole lot to describe!

Answer 2

Try removing the two screws on the left and right.  Just pay close attention to how it comes apart so you can easily put it back together!  Once the unit is removed, take the entire lock to a hardware store or locksmith to find a suitable replacement.  They can be more specific with their assistance, having the lock in hand.  Many replacement locks also come with detailed instructions and pictures for installation.
