Without having enough cover in the pond to provide hiding places for the fingerlings and YOY when the PS/RES/YP spawn, and having the correct cover in the pond to encourage them to pull off a successful spawn is key. I think the numbers of RES/PS are too low, but you may be OK if you have cover in there and wait a year before introducing the SMB.
Here is a typical SMB from a 1 ac pond that has some underwater weeds, but not a lot, and no cover for the YOY/Fingerlings to hide in. It was stocked with more than double the amount of RES and YP you are planning on stocking Plus 5# of Golden Shiners and 5# Fathead Minnows and the pond owner waited a year before stocking between 50 and 75 SMB.
The SMB reproduced in the pond like the owner planned, and the SMB that are 6"-8" long are 110% RW.
The SMB is 4-5 years old.
As you can see, having cover in the pond is critical to the ponds success.
