Manually entering values?

Is there a way to manually enter values for object location, scale, size and rotation? I was working on an object and needed to rotate the thing to get some better views, not I need to reset it to it’s original center of the map, no rotation position.

ALT+R to clear rotation and ALT+G to clear rotation. (ALT+S to clear scale)
SHIFT+S can help too.
Hit N for Transform Properties.
Entering numerical values after G, R or S will transform to those values.

Thank you, organic. Thank you very much, that was EXACTLY what I needed.
