Character names can be difficult and often a name can well influence how a character is written. Some authors spend a bit of time on names and seem to be able to come up with some vary inventive monikers that match the personality and/or physical features of a character. Mrs Laughingale; for an always jolly and giggling wife or Alfred Stickly; perhaps for a skinny accountant.
Many Sci-Fi authors are prone to create tongue twisters, some of which can be rather suggestive depending on the pronunciation used. If it works with the story, names that provide a little tongue in cheek humor can help the story and the reader's enjoyment.
The title can drive an author to distraction and may change with every chapter. But the title isn't important until a book is finished, then it becomes a key factor. A good placeholder, that will remind the author of what the focus of the story is about, will do until it's all done. Then look for the hook, the insight, or focal point of the story, you can use to pull people in.
Covers can be the big attention getter. It's the billboard, that shouts, "You gotta see this!" As mentioned, a beginner has three choices; hire someone, find a friend that can draw or figure out how to do it themselves.
For those who don't want to fork out the cash to hire someone and have friends lacking of such talents, creating a decent looking cover is not beyond most peoples' abilities. Mainly it requires some research and learning how to use a couple pieces of software, of which there are many free versions. A digital camera doesn't hurt either but no drawing talent is required.
