The order that makes the most sense depends on what the loss versus
frequency looks like and how that compares to your loss budget. Going
after dielectric loss won't make sense if you have a deep resonance
issue. Conversely, if you have quasi-linear loss versus frequency, but
just too much, searching for discontinuities and resonances isn't going
to be very productive.
