Need to use all three timers in Arduino

yes i understand that each timers have 6 output, but how do i set that up for my program?

i read the TimerOne library and that library is using the timer1. i need a library like that but using the timer0 and timer2. because in my problems i need to control TRIACs firing signal for 3 phase system. and i realize that i cannot use just one timer.

can you help me setting up the other timers?
