For a static DNS; I suggest using 1 from your ISP; it will be the fastest DNS being you have to hit your ISP before you go anywhere on the net. As a secondary, I recommend 4.2.2.1 That is a dns from Level 3. It is a public that will not change. Plus; being Level 3 takes care of most of VoipO's routing, it's probably a better DNS to use.

For IP address: USA; when you say both your GS are on a hub to your modem; are you saying that you are paying for multiple static IP's from your ISP? Or, is your modem the type like many that has a built in router? You said that your pc's are behing a router. i assume that the router is getting the "Public IP Address" from your modem; OR it too is getting a "Private IP Address" in the 192.168.x.x range. Unless you're paying for multiple Public IP addresses from your ISP; you can definitely give your GS and all your PC's a static Private IP address. Maybe I am misunderstanding your network setup.
