ASA 5505 won't play ball (port forwarding trouble)

[Yonzie]

A while ago, I moved, and after the move I'm having issues with my 5505 and port forwarding.
Before, I had an ethernet drop in the apartment, plugged that into the 5505, and it (more or less) Just Worked (tm).
Now, I have cable internet, and I have to use the cable companys Netgear CVG824G.
This means the 5505 now has a local IP (192.168.0.10).
I have told the Netgear to treat the 5505 as the DMZ, and I have verified that it actually does this.
Unfortunately, behind the Cisco, things are not as bright. I have issues with timeouts in MSN messenger, I can't access anything from outside, etc.
The network looks like this:
Internet <-> Netgear <-> 5505 <-> Switch <-> computer

Someone please tell me what I'm doing wrong.
I have pasted my config here in case it helps. I guess something might have gotten screwed up in the move/reconfig. It seems right to me, but this isn't exactly my home turf

Thanks,
Jens.

Well you're NATing twice, which is one issue. Why use their equipment? If it's a modem/router combo, can you configure it in bridge mode?

no nat (inside) 1 192.168.1.0 255.255.255.0
no access-group inside_access_out out interface inside
nat (inside) 1 0.0.0.0 0.0.0.0

That should do it.
