Looks like you're in mid cycle. Once Ammonia becomes 0, Nitrites will start to fall. Once Nitrites reach 0 and Nitrates might test high, then do a small water change. Then you'll be ready for your first fish!
I have tons of brown algee on the bottom and walls, will this go away, I guess I have not properly cycled the tank, nothing has died, everything seems healthy, I have a couple demsals in there aswell that are doing good.
Damsels are unfortunately commonly used as "starter fish" which is really just torturing them by high levels of ammonia exposure, they will survive because they are are very hardy fish. Brown algae (diatoms) will go away with the cycle.
Good Luck
