Well, it certainly sounds liek she's up for a bit of fun! Though like Overlooker said, you might want to ease off on the rope idea at first - even if it seems that she likes the idea, you don't want to scare her off by coming on too strong.
The only other thing I would add is that while her response suggests that she isn't put off by the idea of being tied up herself, she may not be quite so keen on the idea of tying you up right away. Most girls tend to be submissive - so you might want to experiment a little in situations where you're in charge before you ask her to take a more dominant role.
Good luck! Hope it works out well for you
