Unable to SSH to Google Cloud

Question

I installed the Google Cloud SDK

Thought Web UI I created a new instance. I am not knowledgeable of SSH. I followed steps as described here: https://cloud.google.com/compute/docs/instances#sshkeys

I have Window 7 OS

I checked firewall rules as suggested here: https://cloud.google.com/compute/docs/troubleshooting#ssherrors I checked these through Web UI and found rule

"default-allow-ssh  0.0.0.0/0   tcp:22  Apply to all targets"

STEPS I FOLLOWED:

1) > gcloud auth login (default browser opens up and I authorize the Google Cloud SDK) Google SDK Shell outputs:

"Saved Application Credentails. You are now logged as [someuser@gmail]
Your current project is [some-project-999].

2) > gcloud compute ssh my-instance --zone us-central1-a Google SDK Shell outputs:

 to accept ssh traffic.

On the browser's Web UI, I open the Broser's SSH and I navigate to .ssh folder

someuser_gmail_com@my-instance:~$ cd .ssh
someuser_gmail_com@my-instance:~$ cat authorized_keys

on Web UI, I navigate to Project's > Compute > Compute Engine > Metadata > SSH KEYS and I see three records

USERNAME KEY

someuser_gmail_com ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC4...", "edpireOn":"2015-02-21T23:29:06+0000"}
someuser_gmail_com ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTIt...", "edpireOn":"2015-02-21T23:29:06+0000"}
First Last ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAi...ZkpSpRt6RQ== First Last@MYPC

In my local computer, I navigate to Users/First Last/.ssh/google_compute_engine.pub and I see

ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAit...mGhUKZRgFZkpSpRt6RQ== First Last@MYPC

QUESTIONS:

Does white space in the user's folder path causes problems (i.e. "First Last")?
When the key is created by the Google Cloud SDK, it sets the comment to First Last@MYPC. Is this the correct setting? (I have been reading and trying this and that and I suspect it should be something like someuser@my-instance-public-IP)
