1) Besides the NAS I want to setup and other PCs and laptops there aren't any other devices I want to hook up to the router, but I'll have a mess around with it if things seems less than optimal once I get round to it.
2) I want to avoid using RAID. It just seems like it's going to be more of a complication and additional costs to implement.
Thanks for the response.

Sorry for the late reply, thread didn't seem like it was going to get any.
