I am no expert on this issue but here's what I believe

What are the advantages of running BIND and does it result in better security(firewall-wise)?
I don't think so. Rather you're opening up a potential security hole by running an extra service.
Is it necessary for home-desktops?
Not at all. And there are other alternative name servers too like djbdns - http://en.wikipedia.org/wiki/Djbdns
How do I find whether I'm running BIND?
If you don't know, then usually you aren't running one. Anyways bind runs on port 53. So, you can check that port.
nameserver 208.67.222.222 nameserver 208.67.220.220 nameserver 10.0.0.1
Now what's this about?Where is this supposed to be entered?
This goes in /etc/resolv.conf I believe. This happens automatically once you have edited the prepend line in /etc/dhcp/dhclient.conf.
