Hi Virginia –
Check out the line-up from Digital Juice – You could add lots of effects, like sparkle, using their motion design elements (kinda like clip art for video) – http://www.digitaljuice.com/products/product_volumes.asp?cid=1&pvid=11
They also have two editors toolkits specifically for weddings – http://www.digitaljuice.com/products/product_volumes.asp?cid=1&pvid=4
And a motion background (JumpBacks) for weddings – http://www.digitaljuice.com/products/products.asp?pid=13
If you need RF music, they have really good stuff in their StackTraxx collections – http://www.digitaljuice.com/products/products.asp?pid=13
These are top quality, royalty free assets for bargain basement prices – http://www.digitaljuice.com/products/product_volumes.asp?cid=1&pvid=8 or their BackTraxx collections – http://www.digitaljuice.com/products/product_volumes.asp?cid=1&pvid=1
Good luck!
