Answer 1

Here you can read it.

http://httpd.apache.org/docs/2.2/logs.html

the 404 is the status code and the 480 are the bytes for the content.

2326 (%b)

The last part indicates the size of the object returned to the client, not including the response headers. If no content was returned to the client, this value will be "-". To log "0" for no content, use %B instead.

If you have a lot of that entries someone try to find some security lags and scan your server. To prevent that you could check fail2ban .
