DSL w/831 router configuration questions

Hi all -

- DSL service with 1 static IP address

- DSL modem configured for "bridge mode"

- 831 router

There are some things I don't understand about all this.

#1: In order to make all this work, I need to have the PPPoE stuff configured on the router, yes?

#2: Do I need to have the "interface Dialer1" configured? And if not, can I put the DSL login info in the "interface Ethernet1" section?

#3: Do I need to explicitly set up NAT? I want my internal clients to get IPs on the 10.10.10.0 network and they need to have full Internet access.

#4: I think I don't understand how the routing should be set up.

#5: Any other helpful hints, I'll gladly take!!

Here's my config:

!This is the running config of the router: 10.10.10.1
