This will provide you the opportunity to both accept the extra help, and demonstrate that you already know the skill.

As for the other stuff, just be pleasant and pick your battles. Then make them count. If someone is rude to you blatantly, be as blatant in correcting them but also meticulously decent, respectful and appropriate. "Lois, I can see you don't care for me but I'd like to keep things professional, so please speak to me in a more appropriate tone".

You may find it would be worthwhile to continue looking because these are pretty petty people - perhaps not the funnest to work with.
