A few things:
1. As mentioned, drop your hitch down one notch. THIS WILL NOT AFFECT WD settings!
2. Sounds like the drop/rise on your truck is about right. But you don't really know until you get before/after measurements on the tow vehicle. Compared unloaded front/rear fender height to loaded front/rear fender height and tell us the differences.
3. From the pix, it looks like the spring bars are pointing to the ground. Which means you really need to pick up at least one or two more links. However, you say that it drops the front too much. So, you would need to take some angle out of the hitch head (remove a washer or two) and then you can pick up an extra link or two on the chains. This will require using the tongue jack to raise the truck/tt up in the rear enough to do so.
As you are starting to figure out, it isn't a one size fits all kind of deal with WDH. They truly need dialing in. Getting your weights as mentioned, as well as fenderwell measurements is a good start. There is actually a stickied thread at the top of this forum with a good set of "how to" instructions on setting up your hitch properly.
