Looks fine... sounds to me like this is a red herring, are you sure your
problem is not just with your connection itself? You said:

Inbound unsolicited traffic will be dropped with or without iptables -
you don't need a firewall to stop that as it won't have anywhere to go
anyway. And you'd have to have a serious amount of traffic to choke the
CPU like that. But, that traffic could be using up your bandwidth of
course... If that's a possibility, you need to find out more about where
the traffic is coming from and where it's going to and why you're
receiving it.
