You don't really need to include the refusal letter for the UK student visa, and your husband's letter does not need to state that he has freedom of movement, since they should know that. But including these things won't hurt your application, either.
If you are refused because you haven't shown your accommodation or travel plans, or documented ties to Ireland or any other country, that refusal will be improper and you will be able to appeal it.
