Homegrown Hops - What to use them in?

So, one of the girls in the office today overheard me talking about brewing, and after asking if I brewed my own she said "Are you interested in fresh hops?, we have a couple plants growing at our place, and they are covered in them"

Well, of course I said yes,...but I have done all my brewing with pellet hops, so don't quite know where to begin with the real thing. And the other issue is she has no idea what variety they would be, as they were at the house when she bought it.

So, any idea firstly what they would most likely be (house is in New Plymouth), and secondly, what would be a good brew to do to use these in - and how much should I use (generically, no idea what the AA level is in them). I would was thinking a SMaSH type Pilsner perhaps to at least show off the hops and get an idea as to what they are. And lastly, how do I store them. In the freezer??

Any ideas would be greatly appreciated.
