I think that was one of the auctions I was watching... Congratulations. The GSW's go for a bit more than the GW's, so I think you got a good deal (assuming it's in good shape). I just won a GW, a few days ago. Coming from Japan so it will be awhile...
One of the things you'll have to get used to is using a rangefinder. It's a bit different than the DSLR you're used to, but shouldn't take long to figure out. As TOTC said, meters can be had for a song. Sunny 16 will also get you started.
