You can replace just the pads... rotors will last a long time if you dont drive hard all the time. You still have some time left to get them done, as there is a little pad left.

One time my indicators started squealing, and I wanted to change all the brake parts (rotors, pads, calipers...) and couldnt afford it all yet, so I popped the wheels off and broke the wear indicator off the pads.
