If Halloween is feminine, shouldn’t the expression be joyeuse Halloween instead of joyeux?

I don't understand the use of -t- in forming a phrase.  For example, why is "she accepted" written  "accepte-t-elle" instead of "elle a accepté"?

What is the real difference between "de plus" and "en plus"?  In this writing exercise, the English word "plus" is translated as "en plus,"  "in addition" is translated as "de plus," and "besides" is also "de plus."

How come "en tout cas" is not an acceptable translation for "in any case"? To me, they mean the same thing but perhaps there is a difference in connotation?
