Could always use your stock stuff if you can't locate top hats, but they're usually pretty easy to find online. As for camber plates, I've heard good things about tein, and they're readily available from FR Sport. I scored a set of used cusco's on ebay a couple of years ago, so I know they work too.
Edit: Now I'm looking at these and I see the bottom brackets on the front are slotted for camber adjustment, I might just bolt the stock top hats on all four corners and see if you really need any more adjustment
