Question 1 - You need to use a Divine Petal to reset a quest. You can check how many you have left in Reg/Quest Items. (In this part, you can modify the save files to get Divine Petals more easily)
Question 2
- After finishing the dojo training with Dhalia, X with her 20 times. After that, the dialogue will change, and she will allow you to X with her in the truck. (If you talk to her while X, there will be a hint about this in the back position, if I remember correctly.)
EDIT: You can get Divine Petals by X with NPCs, ghosts, or banish the ghost. To use them, you must exchange them with Tsunade in the Asylum map.
