The Devil Horns weapon, unlocked after completing Classic mode, will make it much easier to blaze through chapters to find any missing collectibles. You might also consider waiting until you complete Classic mode (your second playthrough) to go back and find the collectibles you missed in your Standard playthrough.

Remember, there are many collectibles to be found in the 10 optional missions. You can press 'Y' at the Chapter Select screen to get a breakdown of what collectibles have been found in each chapter. I suggest you find what you can through exploration in your first playthrough, and then use Chapter Select to go back and find anything you have missed.
