Welcome to iBoats . . .
There are a variety of video resources online, but I don't think you'll find everything in one place. So, look around.
+1 on the boater safety course. Do an in-person/live class as it should be more interactive and you can learn from the instructor or other 'boaters'.
Boating is dangerous, it only 'looks' like fun.
Boating is expensive, be prepared to learn how to do your own maintenance and repairs to manage cost. Also, getting things fix at dealers & repair shops is a time consuming process (lots of waiting for your boat to be 'looked at', etc.)
I would recommend spending a smaller amount of money first (maybe around $50K) to see if you actually like boating and get a better idea of the type of boat that is right for you. Then, if all goes well, your $200K purchase will be much more on-target to your needs/wants.
If you are 2 hrs away from the waters you plan to frequent, then you will be either renting a slip/local storage, or having a trailer and haul your boat to/from. If that be the case, factor in your towing vehicle needs.
It seems like very time I get a new boat, I end up buying a new tow vehicle too.
Feel free to ask questions as you go.
