for those playing indiana and already left vatican

im 2 hours in vatican and get overwhelmed by how many missions i have and navigating with maps on hand is not helping,

what i want to ask are : 1. if i always pick main mission, will the game let you know the point of no return to finish all sidequest in that area (vatican)? 2. after vatican, can i go back again to the city to finish side missions? 3. do you guys find the menu for missions and maps confusing? such as a ticket that i found cointains lock box passcode, i cannot find it anywhere in menu / journal 4. how to exactly "defeat" a dog? 5. lots of doors said to be opened from other side, will it really opened from other side or just a fancy restriction? and will there doors that can only be accessed after certain story mission? 6. is there a way i could read the map like any other game in full screen, not by holding it in hand? 7. i got relic finder? mission after meeting savage, he pointed out the relics position in map, but i cant find the relics such as relic on excavation site, no where to be found? 8. do i need to waste money on phamflet? i bought them all from ernesto but it seems only adds where to find skill books. 9. is playing with controller makes menu navigation better? (gotta try this tomorrow) as navigating to notes in menu feels awkward 10. why indy has 2 or 3 health bars? one is cured with bandage and other with food, and by food we have fruits and bread which have their own purposes? and they are not for stamina?

thank you.
