anyone out there that can toss me a small hint... got to the part with the talking rock head... shot the arrow into his eye, went to the bottom cleared the room, no way out of the room, came back to the top, no way over the wall etc... backtracked to the entrance... can't figure out where to go... Z doesn't show me a path... help

When you first entered the area(before E'lara opened the wall by lighting the blazier on the ceiling) take a left at the blazier instead of a right and it should turn you into a U turn and zig zag around the walls until you come to another door you can open.

Basically you want to be on the opposite side of the map from the Ancient One (talking head).

Are you playing as E'lara? That's who I'm playing as and this was difficult for me. Before shooting the ancient's eye, switch to Caddoc. Wander the hallways back behind the stone coffin. Caddoc will give you a "B" button observation event, which should be all the help you need.

what the others didn't say is that you need to pay attention to what the characters vocalize. The area the talking heads are in are "dungeon type" areas, notified by "they couldn't have gone this way", "that path hasn't been used in a while," "i don't think we're on the right track, but lets see what we can find" and such. if you're playing without sound, you're in for a world of hurt.
Once you've collected the treasure, leave the area and continue on your path. If you missed anything major they'll start complaining "lets go back, i don't want to miss anything" and such.

Remember: there's a Fable-style hint button to light the way to your objective if you get lost.
