So there is no /disk0/vhosts/domain/public/administrator directory
at all, am I right?

As far as I understand you basically need to pass everything to
fastcgi while rewriting everything that doesn't exist to
index.php? Try something like this:

root /disk0/vhosts/domain/public;

fastcgi_index index.php;

location / {
try_files $uri $uri/ @fallback;
fastcgi_pass apps;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
...
}

location @fallback {
fastcgi_pass apps;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
...
}

location /administrator/ {
rewrite ^/administrator(.*) $1 break;
try_files $uri $uri/ @adminfallback;
fastcgi_pass 127.0.0.1:3000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
...
}

location @adminfallback {
fastcgi_pass 127.0.0.1:3000;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
...
}

>>> #fastcgi_index index.php;
>>> #fastcgi_param SCRIPT_FILENAME

Do not understand question. All 3 locations mentioned are quite
different in your config - /js/ serves static, while backend.php's
are passed to fastcgi (and one backend.php writes backend1.log,
while other - backend2.log). What do you mean by "merging"?

If you want to avoid duplicate parts of configuration - use
include directive or inheritance from upper levels.
