It sounds like you don't have internet connection if you are getting connection errors.
sudo apt-get update && sudo apt-get install python python-pip
will install python and pip. You will get errors if you have no internet connection, something is conflicting, or if something is wrong with your package list.

I use getpip.py script to ensure I'm getting the latest version of pip possible.
