1. You didn't find anything about fastboot partitions? Man...Come on..... -> http://forum.xda-developers.com/oneplus-2/general/guide-return-op2-to-100-stock-unbrick-t3229606 . By the way, files in zip file are compressed into a .dat format, here a guide to decompress them: http://forum.xda-developers.com/and.../how-to-conver-lollipop-dat-files-to-t2978952 .
2. No, always on unlocked bootloader.
3. Yes, every single time you unlock the bootloader for the first time, EVERYTHING is wipe on your device.
