Hitch angle has pretty much no effect on trailer sway. Trailer sway is best controlled with 10% - 15% tongue weight AND the proper distance from the tongue to the axles. Since you don't have movable axles you need to make sure you load the trailer to maintain that ratio. Too heavy isn't great either, try and stay in the 10% - 15% range or around 300 - 400 lbs for a 3000 lbs trailer.
On a double axle trailer it's critical to get the trailer level. Tongue too high and you transfer more weight to the rear axle, tongue too low and you transfer weight to the front axle. Either one will cause premature bearing and tire wear on the loaded axle.
For single axle trailers it's not critical but they seem to tow better if it's closer to level (and you won't get laughed at going down the road
The easiest way to figure out what drop you need is to level the trailer and Jeep, measure the height to the BOTTOM of the trailer tongue. Then measure the height to the TOP of the hitch receiver. Subtract the height of the receiver from the height of the trailer to get your drop or rise.
Bottom of trailer tongue = 19"
Top of hitch receiver = 22"
19" - 22" = -3" (3" drop)
Now, if you don't have rear load leveling then you may want to subtract an inch to accommodate sag.

I use a 4" drop on this setup:
