To answer some of your questions:
The top peak is 199 feet tall.
Maximum height of track is about 120feet
Maximum drop is 80 feet.
Top speeds around 50mph
One of these threads has a nice fan-made schematic of the track layout. Not sure which one though. Basically, the train will leave the station, turn right and go up a small lift hill. After this first lift, it will go underneath the rock formation the temple sits on and loop around amongst bamboo and other trees before hitting the main lift. The train will ascend up to the main lift, through the temple that will display "higher artistic" paintings of the Yeti. The train will eventually reach the main mountain and take a banked turn inside an icy cavern to the left and up another small hill. During this time, the track switches behind the train and the train then falls backwards into a dark tunnel of the mountain. It will go through a helix (this is NOT synonomous with a loop) and up another hill. After the track switches again, the train will resume forward motion, and drop down the 80 ft lift. The rest of the layout is iffy but involves going in and out the mountain through the back, through two outside helices (again, not a loop) and eventually glide past the 15ft-20ft Yeti AA inside the main show building that is part of the mountain's back. During the whole attraction, the Yeti is "present" in some form ( from the primitive artwork seen in the queue, to the higher scale artwork seen in the temple, to hearing sounds, seeing evidence of track damage, etc.) but you won't actually see him/her/it until near the end of the ride.
As for the standby/FP signs, I don't see the problem. They are pretty similar to the signs seen at Kali if I remember right. It looks more authentic without them, but folks have to know where to enter the ride
