Bala sharks need groups, and those things can get 8" long each.

Common plecos can easily exceed 2 feet in a 40g tank, so they really aren't a good choice, and dwarf plecos are probably too small to be housed with a fish that would eat anything that fits in its mouth.
How big is the oscar? They grow rapidly, so I would imagine even if your was small now, it will outgrow that tank before you know it. So will all the other tankmates that you mention, if you had them in with an oscar. Don't overstock the tank, even temporarily.
The Oscar is still relatively small. Maybe about 3.5-4 inches. I wasn't planning on filling up the tank with anything else yet. I was just thinking ahead for when I move him to the bigger one. Thanks for the info
