I consider the "crossover point" between bass and everything else to be around 300 Hz. So I use very high resolution up to 300 Hz, and then 1/3 octave above that. Measuring accurately at mid and high frequencies is very difficult, so above the midrange you're not usually measuring what you think.

The first thing to do when considering bass traps and other treatment is to disable all EQ or other active "correction" devices. You need to know how the room really behaves. Likewise, if even if you do end up using EQ - and chances are good you won't need that band-aid once you have enough bass trapping - the EQ must be adjusted after all the traps are in place.
