Yes, those are the main parts that you would need porting. Creating a
symbian _cairo_surface_backend shouldn't be too hard as you can rely on
image fallbacks to do most of the work. cairo-os2-surface.c and
cairo-quartz-image-surface.c are examples of surfaces that rely on
fallbacks. 

If you run into any problems or have other questions please ask.

Yes, the core of cairo can certainly be used on a phone. We definitely
care about memory usage and performance on mobile devices.
