propagation

My question is very simple (maybe a tad too simple), but I will try and phrase it in a way to hopefully assist future visitors.

I have just set up (successfully I hope) a DNS server at with some name server records on Ubuntu 12.10 while I am waiting for it to propagate I would like to know for future reference if I can use more than 2 forwarders in my /etc/named.conf.options.Would this speed up propagation?

Do make this question and answer more valuable what other public DNS servers are available over and above Google's public DNS adresses:

8.8.8.8
8.8.4.4

I would also like to know if a restart of bind means that my servers will need to re-propagate? Is there a methodology to update settings while bind is running?
