No, it wasn't a hoax - ergo yes, NASA did land on the moon. There's also no argument - even from NASA - that some pictures have been airbrushed for publication. A lot of the time that was simply down to overzealous managers who thought the images "didn't look 'right'" (whatever their definition of 'right' was at the time - usually involving things they thought would be confusing or distracting to the general public).
As to why we're planning to go back to the moon first. The simple, and sad, fact is that we've forgotten how to do moon missions. The people who planned the original missions have almost all retired by now, and a lot of the processes used to create the specialist materials required (e.g. for the ablative heat shielding) have either been lost to history or now deemed unsafe or insufficient.
As to whether we'll actually make it to the moon by 2019. Well, I hope so, but it needs political will to see it through in what seems like ever-downward pressure on NASA's budget. As it stands today, I doubt NASA has the budget to succeed. We need another space race, so I'm all for the likes of India and China, and even Russia, wanting to 'get there first'.
