Paul, yes. Thats fine, except I see you are using NAD datums/projections.

If these types of geometries were to appear all over the world (and not 
just in British Columbia) what projection do you suggest I use for the 
ST_Transform?

WSG84 is being used for storing the data, but like you said, to do that 
math when it comes to metric distance, what projection should I use?
