Can this router have DNS entries added for local hosts? Some SOHO type routers can do this, but I'm not that familiar with your particular router.

Indeed.

There is no one correct way. But here are a few possibilities for you:
1.) DNS entries in the D-Link router;
2.) static hostnames in /etc/hosts (you'll need to set the router up to always hand out the same IP address for each machine; most SOHO routers can do this, but it may not be obvious how to make it work)
3.) Run a separate DHCP and DNS server on the LAN and not use the router (for a larger installation this would be the preferred way to do things, but for a small number it's not ideal).

Dynamic DNS; your router may be able to do this for you.

Yes. More than one option exists for this; for CentOS 5 at least you can just 'yum install caching-nameserver' and 'chkconfig named on' (and then 'service named start') and it should come up; I haven't used that setup in some time, though, so not sure how nice that plays with DHCP. There are other options, but that is the main one that is in the CentOS distribution's main repo.
Hope that helps.
