As of the RTM build (which you don't have), the freeform tool, pencil tool, and arc tool are now back in the drawing tool gallery where you probably first looked. In the interim, the drawing tools gallery in the Developer tab (turn on dev tab via File > Options > Advanced > Enable Developer Mode, if I recall correctly) has these tools.
Not sure if there is a quick way to get the length of a curve. Hopefully someone else can chime in...
