The red maple -- don't know the pest/malady -- but it's the end of the season, so it's pointless to spray or otherwise treat for leaves which will soon drop naturally.

The shumard oak -- Aphids. Again same reason for no treatment as above. But if you absolutely must do something, wash the critters off with a harsh water spray.
Ants & wasps like the aphiads because they produce sugary honeydew.
The black on the bark may be honeydew which is supporting sooty mold. The mold isn't a disease but is "feeding" on the sugars in the honeydew.

Thanks a bunch. Glad to know it's not serious.

Will they likely return next summer?
