Need help!

Hey ladies! I need help wording our invitations, I've had a headache over this stuff for the past few days and I'm not sure how to go about it. We are paying for the wedding ourselves but both set of parents are helping a little bit but we definitely still want to include their names.
I need help with the wording, punctuation and when to use capital letters, for some reason the second half looks weird without commas! Btw is it ok to use 'we' and also the ceremony is at the Reception hall, this is what I have so far:

Together with our parents
Mr. and Mrs. brides dad's name
and
Mr. and Mrs. grooms dad's name
we,

Bride
and
Groom

Request the honor of your presence
when we exchange marriage vows
on Friday, the twenty first of December
two thousand twelve
at seven o'clock

Sand Castle
505 Franklin Avenue
Franklin Square, NY 11101
Reception soon to follow


Thanks in advance!!!

they have different wording samples, hope this helps!

we got help from both of our parents but we've been paying for everything else.
I put
Mr. & Mrs. (brides parents)& mr. & mrs.(grooms parents request the honor of your prensence to the marriage of their children

Brides name & grooms name.

I put it like that because reguardless of whose paying our parents are the ones giving us away.
