Yes and yes.  I've never heard of anyone getting a bridged connection. 
Maybe with a business account that costs enough.

Yes.  I'm still using a Cisco 678 and you can get one on eBay cheap.  I 
haven't looked at Actiontec specifically but every other cable/DSL modem 
I've seen does DNAT with no limitations.

What is a DNS forwarder?  Can you describe how it works?  Doesn't seem 
like that would be terribly useful in a DSL modem so I wonder if there 
isn't a way round this.

If nothing else, these guys say the thing runs Linux so it should be 
possible to figure out why it does what it does (and eventually to make 
it do what you want):
