Ssh – Be able to pull from git without password on login or just run keychain which does it for me

Try using expect. You can automatically supply the password to git through an automation script.

Just make sure your script has tight permissions -having plaintext passwords in scripts is usually Bad Idea™.

Edit:

Since I can't write code properly in the comment section below, you could write something like this:

#!/usr/bin/env expect
set password "<your-password>"
spawn /usr/bin/git pull
expect "<exact passphrase>"
send "$password\r"

If your only concern is related to people being able to clone or pull from the repository, you can expose a bare repository over a webserver / HTTP. Git Book - Setting Up a Public Repository

There's also the corollary next page: Git Book - Setting Up a Private Repository if you want to grant others push access.

If you don't want to setup seperate accounts for every user, you can use a tool called Gitosis. In gitosis, there is an authorized_keys file that contains the public keys of everyone authorized to access the repository, and then everyone uses the 'git' user to do pushes and pulls.
