Yes there is plenty of parking near the tour bus. Parking is expensive though.
Not really. There are parking lots available.
The dock is in the heart of the French Quarter and although there are plenty of pay to park lots nearby - i always recommend walking in the Quarter as it is fast, easy, and you can pass a lot of interesting sites.
Yes, however it is better to walk there. Area is very busy and lots to see.
Very small parking lot nearby, and a little bit of street parking. I honestly wouldn't attempt bringing my own vehicle. You'll have to walk from a decent distance away.
