Hey shawn. If you aren't finding your answers on this site another resource is a unity custom search here: http://www.google.com/cse/m?cx=002470491425767499270:iugs1ezlsfq&cref=&theme=DEFAULT
I do a lot of searching there and it can help you in finding out the basics.
Your questions seem general enough to warrent a little searching before being asked on this site.

I don't think there's a quick and dirty way to pause. You'll have to:
Then you have to provide the GUI to give the options for Save/Load features or saved games
Hope this helps

Quoting myself from another similar question: 'Making a Pause Menu'
I found all these links by searching UnityAnswers for 'pause game' and 'saving loading' - you'll find a lot of questions have already been answered, just give it a search first!
