Chrissy, you don't have to use fancy, time-consuming recipes for all the cookies. Simple roll-and-cut cookies in heart shapes of various sizes would be pretty, and could be done ahead and frozen. Use your favorite recipe or find one here at TRL; ice some of the cookies and tint some pink, maybe pipe the couple's initials on some.

Linzer tarts are also pretty for special events - they're sandwich-type cookies with a red jam filling that shows thru a cut-out in the top cookie. That's another recipe you can find here. Read thru more than one recipe for them. Some have short-cuts that might help you out. I've never tried to freeze the finished cookies, but you could certainly make the cookie layers ahead of time and freeze them, and then assemble the cookies the day before the wedding.

Another standard recipe (also readily available here on TRL) is the Mexican Wedding Cookie, or Russian Tea Cakes, or Polvorones - all names for the same thing. This is a very tender, buttery cookie, sometimes with nuts, in a round shape, and usually rolled in powdered sugar. Almond Crescents or Horns are a variation on this theme. Any of these can be made ahead and frozen.

Think about including tartlets as well, such as pecan tartlets or tassies. There are several tassie/tartlet recipes of different kinds on TRL. The pecan tartlets can be made a couple days ahead and will keep at room temperature, or they can be frozen. You can also buy baked tartlet shells - usually in the freezer case - and fill them with interesting things like lemon curd, a no-bake cheesecake filling, or pudding made according to the pie filling directions on the box, and garnished with berries or chocolate shavings or chopped nuts.

You might also consider simple shortbreads - simple and elegant, and almost irresistible.

Good luck!
