Default [Q] question about restoring with safestrap

So I am rooted with bajarom on my stock rom slot. I also odin the nc2 baseband.

I am sending my phone back to verizon since they are sending me a replacement phone and I want to restore it back or factory settings.

I did create a backup of my phone using safestrap on the mje baseband when I first got it. Do you think it will be ok to wipe the stock rom slot and use safestrap to restore the original rom?

Do I need to odin back to mje or can I leave it?

Will this also remove the unlock sign in the front?
