I'm new here so be gentle!
I am looking to build an octocopter. I would like it for photography, so it should be powerful enough to carry a large DSLR. I was thinking of the Droidworx AD-8HLE with the AV200 camera mount.
I have read great things about the DJI Wookong M. Can anyone vouch for these? Also, what power distribution board could I use with this. I would like it as powerful as possible.

Also if you have no experience flying any type of multicopter such as a quadcopter it is unrealistic to think your going to jump right in and fly an octocopter with a dslr right away. Most people start with a quadcopter and learn to fly that then they move up to an octocopter.

I notice you say you are new here, not new to multicopters. Only you can determine your skill level and what you want to risk. But if you are, in fact, new to multicopters, I would recommend starting off with something cheap and simple just to get the piloting skills down before you jump into risking thousands of dollars of equipment. You could make one of these really cheaply to save yourself crash money in the long run:
Also, I highly recommend getting a flight simulator that supports multi-rotor copters so that you ca practice without risking anything at all. I use Phoenix:
It only has one quad model, and no FPV. Aerosim RC also has multicopters and does support FPV:
As to your actual questions, the DJI WooKong is arguably the best AP (Aerial Photography) flight controller out there right now. With the right piloting skill and fine-tuning, you could get just as good of results with a less expensive board without GPS hold, but the WooKong makes it a lot easier with autopilot and autocorrection functions, making it much easier to get smooth flight. And it seems to have the best altitude hold on the market right now, according to a lot of people.
Power distribution boards are not even necessary, as they can be replaced with a simple wiring harness. All that matters with power distribution is that the amperage draw of your motors and ESCs will not exceed the amperage rating of the power distribution board. Just like wires. All the power distribution board does is make the assembly process a little more organized than a wiring harness, and makes replacing components a bit easier as well.
For heavy-lift AP, you'll want motors that are low Kv (lower RPM, higher torque) and larger, higher pitch props. This makes the copter less aerobatic, but more stable and smooth in flight. You also want motors with a higher voltage and amperage draw for power, which means you also need higher rater ESCs, wires, and a 4-6S battery. You have to be careful all of your components can meet the same power requirements, or you may need to use voltage regulators to get your voltage for individual components to meet their specific requirements.
Here's a great tool for figuring out if your components will all work together and the final copter will lift your required weight:
