OS X :: Using Distribution Lists For Emailing?

I probably still have my PC hat on but here is my problem.

In Address Book on my IMac, I have set up numerous cards with name address phone numbers email addresses, notes etc. Each card has AT LEAST ONE email address but can have up to THREE email addresses (home,work, other).

I have taken 13 cards and created a GROUP

Two questions:

1. Can I email the address card or copy of the card to an email address for review and updating?

2. Can I send an email to ALL OF THE EMAIL ADDRESS in the GROUP?

I am thinking that to do this (#2) I might have to set up individual address cards for each email address for each group member--yuk. I just want to send to home, office and other by just clicking on JONES or SMITH or better yet the distribution list I have set up.
