In order:

Yes.

There isn't much evidence against it, so I presume so.

Not necessarily. Just because it happened that way, it doesn't mean that's how things go. Unless the light novels specifically say that they need Balance Breaker before using BTB or JD, there's no hard evidence to support that idea.

Also, Issei didn't actually fight Shalba before going into JD, so we don't know whether or not Balance Breaker was ineffective against him. I mean, both times, when Issei used Juggernaut Drive and his Cardinal Crimson Promotion against him during their fights, it was pretty much overkill, so we don't know how effective Balance Breaker would have been against Shalba.
