The brown algae is usually diatoms, otos and shrimps can help clear those. Shrimps are abit more effective when dealing with algae on small plants though, as they are more delicate with picking and eating the algae from tiny leaves.
The oto is probably still getting accustomed to the tank so its swimming around erratically. Once it gets used to the tank it should be less jittery and alot more calm.
If the glosso are being kicked up, then they are probably sitting abit too high above the substrate. You have to plant them deeper into the substrate, with only the top leaves sitting just above the soil.
Here is a planting diagram for reference:
