Start testing in 3-4 days. At first you only need to test for ammonia. Test for nitrite around 12-14 days. Nitrate after that.
I personally would run filters, skimmers, lights, etc. Get the tank "settled" in. This also allows you to see what kind of water flow you have. Running a cannister will not prolong cycle.
If you remove the cocktail shrimp be sure to feed the tank every couple of days a small portion of food. You want something in the tank rotting to feed the ammonia fixing bacteria.
As Sep. said, adding live rock now is ideal.
Watch your ammonia and do water changes if ammonia gets close to 1ppm.
