Doing bathroom rewiring and had to get a new breaker for my electrical
panel. Got both the AFCI breaker b/c I figured it's basically good
insurance and looking at the details and it says "you must have a
licensed eletrician do this!". But it appears to me that it's pretty
straightforward. Wanted to make sure.

It looks like the hot line of the circuit goes into the breaker, the
neutral from the circuit goes into the breaker (instead of the bus),
the pigtail curly-q neutral out of the breaker goes into the neutral
bus, and it hooks in just like the normal breaker onto the bus. I'm
assuming the ground from the circuit also goes into the ground bus
(which on my panel is on the same bus as the neutral).

Yes, I know to stay away from the main two incoming lines as they're
still hot, and to turn the main power off, and to be careful.

But am I missing anything else?

Seems like you've got it handled OK. FWIW, the fussier journeymen
don't like grounds and neutrals on the same bus. Newer design panels
have larger separate buses for neutral and ground. If you want to make
an electrical inspector happy, show him an older panel with installed
extra buses for the separation. But the best argument for the DIYer
adding them is to simplify circuit changes and upgrades in future
years. HTH

AFCI protection is for bedrooms, until the 2008 code kicks in, GFCI
protection is for bathrooms.

But it won't hurt anything to be above code right? The two provide
different types of protection. I've got the gfci covered

I don't know. You could be creating a situation that may cause nuisance
tripping
