CBopp sounds like you have a great pond, very large with good depth.
You've gotten good advice from others so I'll just speak to species I have in my pond.
Golden shiners and Pumpkinseeds are tough and would be good forage for your predators, since you have GSH if you want PS's get a small amount of adults so they should survive predation and maybe spawn this year.
As far as trout I've had Rainbows, browns, brooks, and tigers, the brookies are more fragile when it comes to warmer temps and low O2, browns are real shy, rainbows are tough and grow fast and tiger trout grow fast and will hit your fishing lures faster than the other three.
Maybe try a small number of each if you can get them, and see if they survive, although this is a bad time of the year.
Try keeping a journal of pond temps. especially at depths of more than 5ft.
Feeding your trout can really help them to grow fast but if you have alot of natural forage don't be surprised if they don't eat alot of pellets, mine prefer the natural stuff.
Good Luck and let us know what you stock.
