Actually Latex does a pretty crappy job routinely producing widows and orphans. The only way to change this seems to screw up the pagebreaking.

When was the last time you saw a widow or orphan in a book? I'll bet never for one from a major printer.

There are many things done in books to hugely improve readability that all have to be re-learnt and redone.

Also, yes paperbacks can use the same formatting as the hardcover if the page proportions are the same. Just an FYI hardcovers usually have larger fonts and the page can sometimes simply be scaled down without screwing anything up. So yes, sometimes it is free.
