Thanks, it looks like I'm on the right track.

Managed to get cgminer running and mined a block of 10000 after about 20 minutes using a very old and slow 6850 GPU running at 43Kh/s. I see that the wallet has it's own built in miner but haven't managed to mine any blocks with that yet...
 
At the moment I see 6 active connections and a difficulty of 0.028 so it looks like there is some interest out there.
