Do you want to spend lots and lots of time planning and preparing or do you want minimal work? Consider having the food catered to take some of the work and stress off you. That way you can plan the fun stuff-decorations, drinks, etc. and not worry about the dinner. Has the couple planned their honeymoon? Maybe the party theme could center around the location for that. Does the couple have any special hobbies or activities they enjoy? The party could go along with those.
