This question/answer explains how to create the subimage: Return a subimage from a UIImage

I would suggest storing the coordinates in a plist (as you suggested) and using the above method to create each subimage from you sprite sheet.

(code from the above post)

CGRect fromRect = CGRectMake(0, 0, 320, 480); // or whatever rectangle

CGImageRef drawImage = CGImageCreateWithImageInRect(image.CGImage, fromRect);
UIImage *newImage = [UIImage imageWithCGImage:drawImage];
CGImageRelease(drawImage);
