Hi. Just setting up a tank for two weeks does not make it cycled unfortunately. You have good readings I would guess because it ISN'T cycled. lol
here is an article about the actual cycling process
Cycle your salt tank
Now to answer your questions
Weekly water changes of about 10-15% of your tanks volume with premixed salt water. You only use ro
unsalted water for top offs.
If you have no circulation pumps yet I would suggest 2 550's or 2 750 Koralias. One on each end of the tank.
Adding any live rock AFTER a cycle or for a cycle will have some die off producing some ammonia. thats why it's a good idea to add all the live rock you can when you first cycle.
if purchased AFTER there are living creatures in the tank it's a good idea to let the rock sit in another heated, water circulated tank or container. To avoid an ammonia spike.
Hope that helped a bit Derrick, if you have any questions just ask away.
Oh, as far as stocking it, that will depend on what you want in the tank. Predator tank, aggressive, peaceful- are you ever going to add coral is another question too as some fish are not coral friendly. Also are you running a tank with a glass lid or open top? With an open top you wanna steer clear of known jumping fish.
