how long til the rest of the rock seeds?
Not sure what you mean here. If you did indeed buy some nice live rock it will vary on seeding time with the base rock. A lot of factors come into play in seeding good live rock with base rock. Water quality, flow, lighting, other inhabitants, etc. So for every organism(bacteria, multiple algaes, feather dusters, copepods, amphipods, etc.) that you want to seed on the base rock the timing will vary. The seeding will start immediately, but will take years for it to become the same quality rock as the live stuff you put in.
If you mean, when will the base rock become live rock with no other rock added, then... again it starts immediately. Obviously things that aren't introduced will not colonize it, but the bacteria will start to right away and the rock will become more and more helpful as time goes on.
Thisissimple made some good points. I agree with him that good live rock is nothing but beneficial for your system and fish. I also agree that your planned stocking intentions are too high. #1 Any tang will outgrow this system quickly(same with the trigger). #2 Keeping 2 angels in a system this small is asking for trouble IMO. #3 The Raccoon would be ok in this system, but buy small. It too will outgrow the tank in time. A good stock list for this tank would be the Butterfly, 1 dwarf angel, the fuzzy lion, and a pair of clowns. That would be a full tank.
I agree with both the Fleisbros(ha I think I will start using this!) that it is pretty hard to impossible to have too much oxygen. In your situation you could definitely use the airstone.
I was more saying in a very well circulated system the cons may outweigh the pros when it comes to the airstone. This is not the case here though.
Lastly, not sure if I follow again. The fish should not be causing ammonia that would hurt the "reef". A properly stocked and filtered system quickly breaks down any ammonia that the fish excrete. If you meant the rock will introduce nitrate and ammonia, this is not the case if done properly. The rock must be fully cured first. By you, not the store you buy it from(particularly online) to ensure that the die off is dead and gone before the rock goes into your tank.
The nitrates should be removed as much as possible by yourself via water changes for the fishes sake even if you don't do a reef.
