Too lazy to look for an article for ya right now. A work

Did your ammonia and nitrate readings both go up and back down to zero yet? That would tell you the cycle is complete. I'd do at least a 25% water change it it were me now.
What's in the tank? Rock and sand? If nothing in there now, you can go ahead and remove it from the tank or sump. I used to remove from the main so I could vacuum up some of the debris/waste. I'd aturn the main pump back on and add to the sump unitl the water level was back at my mark. Actually put a high level line on yur sump so you know when to stop adding water so that if the power goes out, your sump wouldn't overflow.
Not sure how much you got in your sump. What, 20g tank maybe with 10-15 gallons of water??
Some swear by the Python units for vaccuming/cleaning.
Also, you'll want to mix the new SW 2 days in advance so it can settle. Need to match the salinity and temp readings to your main. keep a powerhead in the pre-mix also to make sure it's airated/has oxygen. A small Maxi-jet or somthing will do.
Depending on how much rock, you'll be adding a small cleaning crew (maybe 3 snails or so, 5 hermits, and even cleaner shrimp are OK) and maybe your first fish or two at the same time.
What kinda fish do you ultimately want in there. Clowns and what else?? Reef or just fish?
Everybody wants clown fish, right???
Also, I'd remove the smelly shrimp when the ammonia gets real high. 4.0 or so.
