Your crazy. jk
My club thinks i'm crazy too but they just don't care for fpv flying. Note that you will need your ham radio license to do any fpv flying. I already have mine.
One major problem I've had with attempting to do any fpv flying from a computer is that my laptop can't stand the extreme summer heat. It locks up and I have to do a battery pull. I'm currently working on an intercooler for it. Those cheap laptop cooling pads you can buy aren't enough. Most people just use goggles for fpv flying but you'd have to use your laptop on an adruplane set up with maps and waypoints and stuff like that
I would reccomend buying a basic fpv setup before doing anything like buying an autopilot. The best place to buy video transmitters is
here. I wouldn't buy that fat shark crap if I were you though. A 100mw transmitter is, indeed, inexpensive but you shouldn't expect a range of more than 30 feet. This place is horrible about including required cables and power adapters. They give you the bare product you ordered but you have to find most of the cords yourself. I had to buy a 12 volt switching adapter for my reciever. My camera actually came with a cord but the video plug was unike any connector I had ever seen before and couldn't find anything that fit it so I soldered a composite video ending on there instead. The important part is that you actually get what you ordered at all. There are very few places where you can buy this stuff at all so you just have to deal with it and have a good understanding of how to wire stuff up and solder.
Depending on what transmitter you have depends on what battery you need. My 1 watt transmitter is 12 volts so I use a 3-cell 2200mah lipo battery. I get maybe 1.5-2 hours of battery life with that.
The best way to mount cameras on planes that weren't designed for fpv flying or dont have a place to put a camera (i.e. high wing aircraft like mine) is to order meccano parts from
here and build something like this to mount the camera on:
Here is all my equipment. (excluding misc wires and cables) I needed that stuff to get to where I could watch the live feed on my laptop

As for a camera mount that moves around you'd need something like
this, two servos and two reciever channels you aren't using to plug them into.
As for the "arduplane" setup, you'd need an APM 1 or 2 board, and a battery equal to or greater than 6 volts but less than 12 volts. The battery plugs into your reciever which plugs into the ardupilot's input channels chip to power it and override it. There is a detailed documentaion of that thing (both APM 1 and 2) and how it works
here You can get the ardupilot mega board (both 1 and 2) diydrones.com and any batteries from all-battery.com
I can't believe I spent an hour and a half typing that. I hope it makes intelligable sense to someone.
