Tank has been cycling with live sand and live rock for 2 weeks now and I must say nitrates are around 20 ppm, and ammonia is around a trace! Could I introduce some damsels to the tank?

Although that is safe, they could survive at 20ppm, its better to wait.
I dont think your cycle is over yet and other things have yet to spike.

I usually wait a month no matter what.
 
Not sure why you would add a product for removing nitrites when you can't test for it? I would also suggest you stay away from damsels, they can be pretty mean and will limit your other livestock choices...
 
The fact that you nitrates are climbing means you have some nitrite eating bacteria.

Ammonia -> Nitrite -> nitrate

The cycle is complete once ammonia AND nitrite levels are at 0.

Damsels are evil SOBs. Pretty, but pretty evil
