"New Color?"

Ok. So I've been thinking for like two weeks now about dying my hair. Again.
My hair is dark blonde, so I always do gold-like highlights. But I was wondering if maybe a little bit of red, or caramel red might look good?
I was also looking for a haircut. I now have it past shoulder length, and, I'm tired and bored of it. I was thinking of doing something maybe like Kate Moss' blonde bob? Or maybe something like Keira Knightley back when she had it about chin length.
If you have any ideas, please speak up.
