what is command that may allow me to see the detailed information of my installed Emulex HBA cards on a Red Hat Enterprise Linux4 setup? esp. on the WWNs of the cards and the speed ?

you can check the files under:

/sys/class/scsi_host/host1/device/fc_host*

in Redhat with qLogic HBA's
cat /sys/class/fc_hosts/host1/port_name
cat /sys/class/fc_hosts/host2/port_name

This is the methods I use to get details about the HBA's

To get HBA WWN info on host run:
“systool -c fc_host –v”

Rescan HBA w/o restarting server run:
systool -c fc_remote_ports -v –d

Or

cat /sys/class/fc_hosts/host1/port_name
