Hmm.. not sure about older versions of CentOS but for lvm over iscsi in
5.2 all you should need is 

/dev/foo.vg/foo.lv /foo xfs _netdev,noatime,rw 0 0

in /etc/fstab and iscsi node startup set to automatic (which is the
default I believe). _netdev being the key as it will mount it after
iscsi is loaded and connected. 

And since the volume is being asked to mount at boot time, the startup
scripts are smart enough to find and activate the volume group and
logical volume.

Nothing extra required. 

Only issue I've had is sometimes after unclean shutdowns the volume
group gets deactivated and must be manually activated and mounted,
though this has never prevented booting.

Though this doesn't include the fsck'ing you mentioned..
