easy topic to answer so soon after St. Patrick's Day!

Hire some Irish dancers to do a little show--that was the most impressive thing I heard for St. Patrick's Day.

You could incorporate clovers into the floral. 

You could play some irish music, if you like punk play the Dropkick Murphys or Flogging Molly.  But, there are plenty of more traditional irish songs and musicians that you can play.  I like Kate Rusby, she's English but her music sounds kind of Irish folk to me.  There's also more obviously U2 & The Corrs.

My friend had someone read an Irish blessing during her ceremony, or have someone read that as a before dinner "prayer."  Or find a traditionally Irish quote about love and incorporate that somewhere.

Irish Marriage Blessing

May God be with you and bless you.
May you see your children's children.
May you be poor in misfortunes
and rich in blessings.
May you know nothing but happiness
from this day forward.

You could maybe incorporate some kind of celtic knot into your wedding decor.

As for Irish treats, I can't think of anything that is specifically Irish outside of potatoes :-)

I think the handfasting ritual is of Irish and Scottish decent.
