1. What think of stocking plan?
400BG, 200HBG, 200RES, 30#FHM, 5#GSH
Followed by 75 HSB in fall this year or spring ‘20?
4. Thoughts on LMB fall 2021 or spring 22?
Snipe has a good suggestion IMO to for starters leave out the HBG. HBG can be a good fish and if you really want them add them when you add the LMB. For some good initial panfish diversity I would reduce BG to 300 and make RES 300 and IF you can get them add 200 yellow perch(YP). You can get all sizes of excellent pellet trained yellow perch (3"-12") from Brehms Perch farm north of you in West Liberty.

In your plan, IMO the YP will be primarily an early pond history panfish. But while you have them, they will be a favorite panfish.
Once you add the LMB expect the YP to gradually decline in numbers until the old breeder adults die out unless you ladder stock. IMO it is better to have had some great YP compared to have never had them. Once the YP start to be noticeably fewer in the angler catch results then that would be a good time to start adding HBG?
LMB love to eat YP rather than BG. Since you are using BG, I am not sure how well HSB alone will control the BG, thus the LMB will likely be needed. I think HSB will also 'tend' eat more young YP compared to BG. Thus YP will after 4-6 yrs struggle to annually recruit very many small perch. Qualifier - I have very limited experience with YP and BG together in ponds.
If you want to try the pond without LMB, the good thing about the HSB alone is you can keep ladder stocking each year enough numbers of them until you get good control of the annual BG recruitment. If it is not working you can always add LMB at just about anytime. If you are feeding pellets the BG even though abundant in 1 ac should continue to get good overall growth rates due to the pellet feeding, but remember to harvest BG (see below). In one acre you may have to add pellets in two different locations to get a high percentage of the fish receiving pellets to maintain good growth rates.
First year pellet feeding will likely not require more than 50-75 lb of pellets of Aquamax 5D05 3/16", or Optimal Bluegill. Don't forget if you regularly pellet feed the fish, remember to practice annual panfish harvest to keep the fishery from becoming over a reasonable carrying capacity. One acre with aeration and 250-300 lbs of pellets each year should allow around 80-150 lbs/ac of panfish harvest each year once BG reach 8" (yr 2or3). Predator harvest should be appropriate for your goals of the fishery as in an emphasis of mostly larger panfish or larger predators.
