Should Wedding Programs Match Invitations PLEASE HELP ME ASAP!!!?

PLEASE HELP ME ASAP!!!? - should wedding programs match invitations

OK, it sounds stupid to some, but the really important for me!
My friend and I are launching our own engagement party .. I know usually the parents of the bride and maid of honor to do so, but my mother just had a baby and) also my maid of honor (my aunt, so they are busy ANYWAYS

Question No. 1 ---- we have a luau theme in a park near our house .. I have some invitations that were bought when I thought we were going to make an issue of Hollywood glamor, but money is scarce and the lease of the theater is out of question! So I have the same ?!?!?! Or only certain calls that go with the theme?? But it also has something in every game so far in my sets and I wanted to match my clothes at the engagement party to .. but the invitation only doesn'tgOr with the theme ..

Question 2 ---- I would also formal wording on the invitations .. Do you think it would be cool, or out of place for a party so relaxed?
Here's the stuff ..
