Your questions were well addressed above, but I'll chime in too, just to make it unanimous. -
0. we'll point you to helpful threads, depending on your needs
1. you're fine
2. see below for dish aiming info
3. good skills. FTA should be educational, but not that big a challenge for you
4. yes he is; yes it is; the glowing review is by our best people! -

5. DXing via OTA doesn't hold a candle to FTA (unless you are just nostalgic for the old days)
One thing I'd like to bring up that hasn't been touched on yet, is where to mount the dish.
For a beginner, it's really a good idea to have it easily accessible for your first efforts.
That means mounting it to a wall or on a post in the back yard, about chest high.
Roof-mounting a motor as your first venture into FTA, will be a monumental challenge.
Even with your experience, getting to know the receiver will be a big enough challenge for your first step.
So, I would really suggest you leave the motor in the box and install the dish alone to gain familiarity with the receiver.
Plan on taking the FTA receiver and a monitor out to the dish, to help alignment, too.
Watch one satellite and work through all the menus for a week.
Use the time to study how to install and align the motor, and maybe on the next weekend, dive into it.
Finding yourself unprepared right in the middle of the install/alignment, will be frustrating and painful.
Here's where to look and find the various satellites in the sky....
