Do you select (green "checkbox") all three disks on the first destination screen before you enter manual partitioning?
Yes.
I just ran gparted again and scrubbed sda and created a swap partition (primary) and physical volume, then a logical volume within the pv using 4 GiB (about 2/3 of the space). I formatted that ext4 and labeled it as root. Now I'm waiting for the CentOS installer to load to see if I can do something with that.
