No and yes, I'd you flash the rom first you'll be fine. The rom zip contains boot.img so if you first restore the boot.img it will be overwritten if you flash the rom second. Therfore you should replace the boot.img in the rom zip.
How it helps and clarify the situation
Do to others what you expect yourself, thats respect. Remember the newbies, we dont know what they might know
