I messed up that ssh command and wrote it to memory. How to I remove the mistake line from the config?

Tried, but key already generated. Is that a problem?

happypix(config)# ca gen rsa key 1024
For <key_modulus_size> >= 1024, key generation could
  take up to several minutes. Please wait.
% You already have RSA keys defined for pixFW.happypix.org.
% Please remove the keys by issuing ca zeroize rsa command
%   before generating RSA keys again.

I have tried to putty into the pix from the internal side and it's asking for a login and password.

There was an existing account called ipsec that I do not know the password for, but I also created another account called: james

I know the password for james, but when I try to login using putty with that account I get a accessed denied message.

You can see the account name in the config posting I made, Is there something wrong with the account or do I need to add it to a group or something? If it needs to be added to a group I am not sure how to do that.

1. I am now trying to get into the device manager and it's asking for a user name and password. I do not know enough about the pix to find out what the username is and the password. I have tried the default user name and passwords for device manager with no luck. Can I find out the user and pass from the terminal? If yes, How?

Try username pix, and the password you used to login.

2. How do I check if VPN is enabled?

It looks it is enabled, or configured. Did you try to connec to it?

2.1 How do I check what accounts are enabled for VPN if it is enabled?

vpdn group PPTP-VPDN-GROUP client authentication local
 
tells to user local username/password. From your config, only one user is setup.
vpdn username monitor password ********

3. How can I enable telneting into PIX from internet? I can only telnet from the internal network.
Add the following command;
telnet 0.0.0.0 0.0.0.0 outside
