Djose Highroad and Temple
Save your game at the Save Sphere again before you continue down the Highroad. You will encounter fiends down this road called Basilisks (shown below). They cast Stone Gaze on party members which will petrify them. If all of your party members have the Petrify status its game over. Though that outcome is fairly unlikely, petrified party members will also not gain any EXP or AP, which means using Soft on them to remove the Petrify status is a must.
Continue down the road until you reach a chest that contains two Phoenix Downs. Just past the chest is an Al Bhed Primer vol. XI just behind a pillar. Use the screenshot below to locate it.
Talk to all of the people that you pass for some items including a Soft Ring, Ether, Hi-Potion, Mega-Potion and a Bright Bangle (the treasure chest for this item is hidden off to the side).
You are in for a few more cutscenes and story telling when you reach the fork in the road.
Djose - Pilgrimage Road
There is nothing to gather on the Pilgrimage Road so just continue to the temple of Djose. Talk to Lucil and the Crusaders as you past.
Use the Save Sphere and save your game before you enter Djose Temple. You will also want to venture to the north-east side of the temple beside the shop to find a treasure chest. There are four Ability Spheres inside. To the far left of the temple, past Lucil and the Crusaders with the chocobo, is another treasure chest containing 4,000 gil. Enter the temple when you’re done.
Make your way to the left and to the right of the stairway after the meeting with Isaaru. The room to the left contains a treasure chest with a Remedy inside. The room on the right side contains a treasure chest with a Mega Phoenix in it. Time to head into the Djose Cloister of Trials.
After completing the trials you will run into Dona and Barthello again. Try to leave the temple chamber to continue the story again. You now have Ixion as a summon.
Go back inside the temple when you awaken and enter the room to the left of the Cloister of Trials to find Yuna sleeping. Save at the Save Sphere and then re-enter the store/inn to grab the treasure chest at the back of the room. It contains Switch Hitter.
Now head back towards the Y intersection.
Djose - Pilgrimage Road
This time when you cross the Djose Pilgrimage Road quite a number of the people you speak with will have items for you. The first man on the far end of the bridge will give you a Halberd. Further on down you will receive ten Potions and the monk walking back and forth will give you two Hi-Potions.
On to the Moonflow.
