By default, ssh will try all available authentications IN ORDER (what the default order is, I'm not sure). To make sure that it doesn't try password, add the following options to your ssh command

-o 'PasswordAuthentication no'

and

-o 'PreferredAuthentications publickey'

Also, some servers and clients can be picky about permissions on the key files. Check your documentation to make sure your permissions are correct.

One other thing... It seems like it would be more secure to keep your private key at the client and put your public key on BOTH servers. Then, using authentication forwarding you can login to server A and then from server A to server B seamlessly. Remember, the strength of publickey authentication relies on being able to keep the private key private. Leaving private keys laying around on servers (especially if it's not password protected) seems like a bad idea.

NAME
ssh-import-id - retrieve one or more public keys from a public keyserver (Launchpad.net by default) and append them to the current user's authorized_keys file (or some other specified file) SYNOPSIS
ssh-import-id [options] USER_ID_1 [USER_ID_2] ... [USER_ID_n] OPTIONS
-h | --help usage -o | --output F write output to file 'F' (default ~/.ssh/authorized_keys, use "-" for standard out) DESCRIPTION
This utility will securely contact a public keyserver (https://launchpad.net by default) and retrieve one or more user's public keys, and append these to the current user's ~/.ssh/authorized_keys file. The system administrator can change the source URL used by ssh-import-id(1) by editing the configuration file, /etc/ssh/ssh_import_id, which is sourced to obtain the value of URL. By default, URL="https://launchpad.net/~%s/+sshkeys". Note that this url really MUST be a secure, https url with a valid, signed certificate or else your system will be vulnerable to man-in-the-middle attacks! The "%s" will be populated by ssh-import-id(1) with the value(s) of USER_ID_1 [USER_ID_2] ... [USER_ID_n]. SEE ALSO
