I'm no expert but mabie I can help a little

Forrage: Suckers can be just like carp so I wouldnt want them in my pond. Gizzard Shad have thier place in pond management but are not to be taken lightly. You should wait untill at least 25% of your bass population is over 16" and then begin to consider gizzards. Threadfin are awesome but if your water temperature gets below 42 in the winter the will all be dead. Shinners are somewhat difficult to get established if you already have a bass population. Some people, like greg grimes, say to be cautious with them in the south because they grow a little too fast but I THINK at your lattitude they'd work great. What do you think greg? Fatheads will multiply like crazy in the absence of a preditor but if you already have bass dont even try. I'm not as farmiliar with alewifes but I belive they are very similar to threadfins but they can die in the heat rather than in the cold. Big thing to remember with forrage is that in the regular bass/bluegill pond Bluegill are the primary forrage base and everything else is just diversity.
Sunfish: Coppernose are great but I have no information for you about them dying under the ice. Redears stay small and Longears stay really small. They also wont spawn so prolificly as the blugill so they wont produce quite as much babies for you bass to eat but if you absolutly have to have them they wont cause any serious problems.
Aeration: As far as I know, weed prevention is not the main purpose for aeration. Destratification is, and it is a big thing. Aeration and Destratification help breakdown amonia, breakdown bottom sludge, lengthen the life of your pond, prevent total ice cover in the winter, and most of all prevent an oxygen kill. The only time that it can be a little tricky is if the pond is already stratified and you are just turning it on. You need to start out running it only during the day and turning it on little by little. 8 feet is shallow enough that I think a fountain is the better choice. You also have considerably less risk when turning them on because 8-10 acres is large enough that what you can do is only turn them on in half the pond to start out with and once that side has been fully mixed for a while then you turn on the other half.
Suplemental Feeding: Feed them. Feed them all they can eat. You will see the benifits. My pond is 8 acres and I feed them 3 times a day at 3 different spots. Try to be consitant with them so that they will learn faster. Feed them in the same spot(s) at the same time(s) and they will learn to come in droves. The water will boil with activity, its tons of fun. Once the water temperature gets above 50 you can start.
Fertilizer: If the clarity is shallower than 18" you don't need fertilizer. If the clarity is deeper than 18" than fertilizer is a good option. When used properly fertilizer should not cause problem with weeds and stuff. just dont over do it. Too much fertilizer could give you dissolved oxygen problems. But before you go and fertilize do an alkalinity check. if it is above 20 ppm go for it, if it is below 20 ppm lime the pond before you waste your money on fertilizer.

The only other advise I can give is just keep on reserching and have fun with your pond.

Take great care of it, or let someone else have it.
