Invitation wording help

I am getting married in September and I have been stressing over 2 things. I am going to pull my hair out soon!! My parents are divorced and both remarried, mu fiances are not. How should we word the invitations...'the parents of...' or should it just say 'the honor of your presence is requested...'

Also I want to see who can help me with this one. My dad is comeing here from Arizona for my wedding, and obviously I want him to walk me down the aisle.$However, my step dad whom I have lived with since I was 10 (Im now 27), and has helped thru alot, I would like to have walk me down the aisle as well. My problem is that 1) I dont want to hurt feelings, and 2) its going to bad enough to have all my parents in the same place at the same time.

HELP ME!!
