Ramiro,
Give the rock a good, good rinse. After that, you can go ahead and throw them in the tank. The rocks will cycle in the tank just fine. There would not be any benefit to cycling them outside of the tank because you do not have any inhabitants currently. However, it would be a good idea to go to your local fish store and purchase a few pounds of live rock there. Maybe about 5lbs or so. Make sure the live rock has a good amount of coralline algae. This way you will be able to add beneficial bacteria and coralline algae to the dry rocks.
For equipment, I have a few recommendations.
You mentioned your pump is loud. I use a "KEDSUM 550GPH Submersible Water Pump". It is very quiet and cost effective. If you are interested in replacing your current return pump, check it out on eBay.

Kedsum also makes a 770GPH model for about $26 on eBay.
You will also need a protein skimmer. I have a SCA 303 skimmer on my 75 gallon and it works well. A SCA 303 (rated for 150g) or SCA 302 (rated for 180g) would work well for your tank. Those skimmers are both $174 each on scaquariums.com link:

For lights, if you want leds, you can get two Radion XR30w g4's if you aren't worried about the price. If you want to remain cost efficient, you can get two Mars Aqua led fixtures online for around $90 each fixture. These lights are supposed to be hung from your ceiling. You could also buy some electrical conduit from lowes and put a 90 degree bend in the conduit, secure it to the back of your stand, then hang the lights on it. That is how I hang my lights.

T5 is also a good option for lighting.
Sorry if that is a lot of information. That should help get you started though.
Edit:
I forgot to mention you will need to have water flow in your aquarium as well. If you plan on keeping hard corals or sps corals, you will need a lot of flow. Less flow for soft corals and lps corals. You can get these for a good amount of flow:

However, I would highly recommend these Jebao PP8's:
