Which way do I turn the main valve to close? It naturally seems logical to turn clockwise as the dial will tighten but the sticker says different. Don't want to damage it when it is connected. The needle valve seems normal, clockwise for close? Sorry, just got my system and just trying to understand the dials first before installing. Thanks.

the sticker is correct. you'll essentially unscrew it until you feel no pressure.
 
Do I leave it unscrewed then, closed, when I open the co2 tank valve? I'm guessing yes. Open tank first then regulator then check valve?
 
Leave it unscrewed. The needle valve on the bubble counter should be on the highest setting. Before you put any liquid in the bubble counter though, you should blow out any potential dirt from the regulator by opening it way up. Then close off the main. Add your liquid to the bubble counter. Then open up the tank valve and use the main on the regulator to get as close as you can to the bubble rate you want. Use the needle valve to do a fine adjustment.

Just to have this straight. While co2 cylinder, unscrew regulator toward (-) until no pressure. While needle valve wide opened, open co2 tank valve, correct?
 
Correct, then once the tank valve is open, open the main on the regulator by screwing in the knob. CO2 will start to flow. If you've already done the blow out process that I described before, then use the main on the regulator to get as close as you can to your desired bubble count and then use the needle valve (the smallest one) to further refine it down.

Got it running, easier than I thought. Tank pressure is about 800 psi, working pressure is about 30 psi, bubble count is about 2 bps. Look or sound OK?
 
sounds about right to me. Keep a close eye on it for the first couple of days. If there's some dirt that got stuck inside the regulator it could blow through and you could get a pretty rapid increase in CO2 flow rate, but if you did the blow-out procedure that I mentioned you should be good.
