replacing rotors is prolly 5-7mins per side(with air tools and lift anyway).
I trying to think what can be screwed up doing rotors
maybe cross threading putting the calipers back on. so just take your time.
Its 2 bolts to remove the caliper, 2 to remove the caliper brakes, remove rotor. reinstall
difficulty scale of 1-10. 1 being changing oil, 10 being changing clutch.
I'll rate it like a 2.5, maybe a 3 for it being the 1st time.
I say have at it. tools I recommend, breaker bar and something to re-compress the pistons
