Auto Problem Question?

I have a 99 Monte Carlo.. On the way to work this morning the VOLT and the ANTILOCK dash light came on.. On the way home The radio kept cutting out and the same light were still on. WHen the car died and tried to restart all I got were clicks…..
Took battery out and had it checked they said it was good.. The next thing we are going to take out is alternator.. ARe we looking in the right direction? Asking cause hubby doesnt do mechanicing very well but cant afford repair shop right now.. Any help would greaty be appreciated.
