Default Belt changing caveats

Are there any caveats to changing the belts on the 02 wrx? Specifically the ac compressor belt?

I'm reading a lot about broken tensioner brackets in the forum...

I think the main reason that people break the AC tensioner is they forget (or don't know) to loosen the lock bolt before cranking on the adjuster. The bracket is plastic, so it breaks fairly easily when you do that.
Aside from that, if the car is high mileage and/or has been driven in the winter on salt-covered roads, the tensioner bolts may be rusted and difficult to break loose. PB-Blaster or equivalent may help. Also with the belt off, check that the idler spins smoothly/freely and quietly. If it's rough, noisy, stiff or has play it should be replaced.
Otherwise, replacing the belts is not a big deal. Use the OEM ones from the dealer, they aren't that expensive.
