You could probably make some of that into a function that accepts a
timestamptz and generates the two days.

You'll be better off if instead of 2 days it gives you a daterange: http://www.postgresql.org/docs/9.4/static/rangetypes.html

I don't know about the exact ISO details, but your approach is the correct one: find the date that the current week started on and then build a range of [week start, week start + 7 days).

Also, note the use of [ vs ). That is the ONLY correct way to do this if you're comparing to a timestamp.
