Answer 1

Assuming that you already have a working PHP configuration...
If your domain does nothing else, the default action could be to invoke the script with:
location / {
try_files $uri /rates/callrates.php?c=$uri;
}
The above has the side effect of leaving in the leading /.
If you want to make the rule more specific, you could protect it with a regular expression (which also extracts the country name correctly):
location ~* ^/(?<country>\w+)$ {
rewrite ^ /rates/callrates.php?q=$country last;
}
