configure IPv6 using DHCPv6 on a TP-Link TD-W9970 router

Anyone know how to configure IPv6 using DHCPv6 on a TP-Link TD-W9970 router?  We're upgrading from ADSL2 to FTTC on Tuesday, and I'm not sure the steps I'm planning to take are sufficient.  Here's what I think is the relevant page (sorry - screenshot wouldn't paste):

The parameters of IPv6 LAN can be configured on this page.

Note: Only the default group will support IPv6 at this moment.

Group: Default

Address Auto-Configuration Type: RADVD  DHCPv6 Server

Enable RDNSS:

Enable ULA Prefix:

Site Prefix Configuration Type: Delegated   Static

Prefix Delegated WAN Connection:

IDNet has told me to check the boxes for DHCPv6 Server and to enable RDNSS and that the configuration type should stay Delegated., but I don't know where to put the Route, Prefix, and DNS Server information that IDNet has sent me - they are the same as our current DNS IPv4 and DNSD IPv6 settings on ADSL2, but I'm not sure whether they'll still be there once I configure the router with the new VDSL settings (though we're already on PPPoE rather than PPPoA). Are there any other router pages I should change?  Thanks for any advice you can give me!
