Doubt about SAO Hollow Fragment

Hi everyone, (sorry about my English in advance), I d

like to ask about new game plus in this game. I suppose that I ll have to clear all Hollow Area and Aincrad again and I read something about enemies 10 lvl higher, but I m concerned about a few things:

- My affinity levels with heroines are reset ?

- Do I have to make all again to get the events ? I mean the event progression is reset as well ?

- Which is the best place for XP farming ? I m level 140 with 2 xp rings and a XP charm and it takes a lot farm xp.

-Best builds and weapons ?

-And last but not least, how do I play the minigame to improve heroines mood correctly because I feel kinda trapped not progressing.

Thanks in advance and sorry for this long text.
