Yes — flashing, backup, ringtones, wallpapers and device verification are all free without registration.
The official build is safe. Always run a full backup before flashing and keep the battery above 50%.

No — sign out of iCloud before flashing, or activation will still demand the original Apple ID password.
Use the original cable, tap Trust This Computer on the phone, reinstall iTunes drivers, or try a rear USB port.
