Whats next? 3 weeks old tank ...

A lot of people will tell you that your tank is most likely still cycling. It seems like you got a ton of stuff there, which is simply risky ( some stuff could die due to tank conditions ).

Water changes are always a good idea. You're taking some of the good and some of the bad out of it. It will lower any possible levels of amonia/nitrate ( since you're removing that bad stuff ) and adding in new fresh water. Your inhabitants will appreciate it.

The suggestion is always to "go slow". Take your time. There is a lot of stuff in the tank already, new additions cause new cycles to take place, so it's a good idea to one/two things into the tank and give it 2 weeks - 1 month before adding anything new.

I'm itching to get coral into the tank, but everyone has been recommending to wait. A stable tank will go a long way.

If you are getting a ton of hair algea, it is probably because you have a high phosphate level. Try to maintain that by adding a filter ( like a Halgen filter ). You can also just get a phosphate removal pad and stick it into your bucket when you're processing the salt. This way, by the time you put into the tank, a lot of phosphates get removed. Try borrowing a phosphate kit or pickup a new one, it could be that your phosphate levels are high. This isn't necessarily a bad thing, it gives your turbo snails a run for their money.
