Whether the Factory Reset will do any software damage to the phone and whether Factory Reset will lose all the factory installed apps and factory pre-installed apps.

Why did you start another thread with the same question?
Anyway, as MaxH already told it'll erase everything in your device except the apps that came with it out of the box.
You will lose all your contacts, synced accounts, photos and such and as well all the apps that you manually installed and you'll have to update the built in apps all over again as well.
To reassure you, a factory reset will basically take your device back to how it was when you took it out of the box.
