First, it's not good practice to have 2 DHCP servers on the same network, even with scopes restricted to avoid duplicate IPs... you can't make the Linksys hand out addresses only to clients connecting directly to it... when a DHCP request comes across the broadcast address, it will be a race to see which DHCP server can respond first... whichever is faster will deplete its scope first, then the other one will pickup and begin assigning *its* scope. Better to set them both up with identical scopes and then just disable one of them, so you'll have it for backup if the other one goes down.

In the WRT610N's configuration, on the Setup 'tab', over to the right on the Advanced Routing submenu, disable NAT.
RIP may or may not help (depends if the Netcomm supports it - if it does, set the Linksys to use it in both directions, and the Netcomm to take it 'in' only... you don't want it sending RIP updates about your LAN to your ISP). And you may need to setup a static route there too, but try it without both of those options, first. With NAT enabled it assumes there's a different network on the other side of the WAN port.

For connecting to modems that are in bridge mode (i.e. either without routing functions or with the routing functions bypassed).

None, unless your ISP uses PPPoE (which nearly all digital subscriber line providers do).

If you're asking how to setup DDNS for dyndns.org, see http://www.dyndns.com/serv
When you get to step 3, do not install a client - enter the settings you just made on the Netcomm's DDNS setup page.
If the Netcomm doesn't have a DDNS setup page (that would be odd - I haven't seen many home/SOHO routers without that feature for a long time), you might look in its setups for a way to disable the routing section - usually called 'bridge' mode - and possibly use the PPPoE screen as mentioned above. Then you could use the DDNS setups in the Linksys... you would also need NAT enabled (and RIP disabled) on the Advanced Routing submenu in that case.
If you can (and do) put the Netcomm in bridge mode, its LAN ports technically become part of the WAN. So you cannot connect your TP-Link switch to the Netcomm like that (unless you get a /29 or /30 IP package from your ISP)... you would need to feed the switch from the WRT610N's LAN ports instead. So if your plan was NOT to have the Linksys and Netcomm anywhere near each other, you would have a quandry... you'd either need to have them near each other or pull another cable from the Linksys' location back to the TP-Link to replace the Netcomm's connection to the switch.

I might also ask the following:
In the Internet IP Address config section for the WRT, besides having Static and DHCP options which I have already played around with - it also has other options - including PPoE (which is used by my NB5 to connect to the ADSL). Why would the WRT have this when it clearly says that it doesn't replace my modem device? What advantages could I receive from using this option (I'm thinking one is dyndns.org) and how would I set that up?
Thanks
