1) The word fruitcake has come to mean someone who is round the bend, out to lunch, completely fucking mad. It came from the old British slang"Nutty as a fruitcake"(fruitcakes have got nuts in, ya see), because, as you know we've used the slang term "Nutters" for the insane for....well ever, really.

2) I do believe that some American people call gay people fruitcakes. I know that the term "fruit" has been used as a slightly derogatory term for Gay men(in the UK any way), but I'm really not sure where the "cakes" bit came from, or why!.
1) "Dave came round the other day, goin' on about these multidimensional life forms that are controlling his libido or somethin'" "Oh yeah, Dave's a total Fruitcake dude."

2)....Err not sure really!! I've never heard "fruitcake" used in this context. But "Fruit":

Err 2, take 2) "Look at John mincing about,......Oi John your a proper fruit mate"
