You'll probably have to just find books on Iwo, Okinawa and Tarawa to start.
There was a Sherman on Tarawa called "Colorado" if memory serves that was something of a legend as it was the only tank working for much of the battle, with the other Shermans water logged or knocked out. It was fairly instrumental in the taking of the airstrip.
The Shermans on Iwo took some serious hits from artillary and struggled in the volcanic ash, but again as time wore on played a big part.
There was very little tank to tank stuff as the Sherman in the Pacific was to the Japanese tanks, like the Tiger in the ETO was to the Sherman. It was really no contest most of the time.
I know they were on the Canal too.
I'm at work so I don't have titles in authors in front of me. The only one I can name right now is "Iwo" by Richard Wheeler.
