So I basically had to cruise the net finding the proper way to address my invites, because let's face it, I was clueless.  Here is what I found on the same page:

• Write out names in full, including middle names. Omit a middle name if necessary, rather than using an initial.
• It's appropriate to use the British spelling for "honour" and "favour", unless you prefer to use the American spelling of these words.
• Spell out all words, including the hour, the date and the year. Spell out all words in the address, including Street, Road and Avenue. The two exceptions to this rule in an address are Saint (St.) and Mount (Mt.)
• Use Roman numerals in names, rather than "the third" or "3rd."
• For ceremonies taking place in a house of worship, use "request the honour of your presence." Ceremonies taking place in a non-religious setting should say, "request the pleasure of your company."

Woops.  Screwed the pooch on that last one!  Did anyone else throw the traditional etiquette out on their invites?
