Ok I think I have everything running now. I'm getting a lot of stales, but I'm not sure if it's the chain itself or my GPU which has been acting strange lately. So has GG patched the possible 51% exploit along with the timewarp exploits that Art talked about?
High stales are normal at low difficulty.
I think it has something to do with the time between finding new blocks, also.
If you submit a share (or is it a nonce?) for a block that already was found by someone else, yours is too late and probably becomes a stale.
I had a lot of stales when mining i0coin and solidcoin with high networkpower and low difficulty too.
