YES, the spraybar is still jetting out water during the water change. I call that the WATERFALL! It makes a happy nature sound through the house all during the water change and reminds me not to go off and get distracted from my task (as you all can tell I'm easily waylayed by curiosity, lol.) In fact, I have an external "inline" heater spliced into my filter outlet hose and movable lights on the top, so I don't really have to unplug anything to perform a water change, just get to it! (well, lately I've been placing my circulation powerhead pretty high up, so I have to remember to unplug him!) But, yes, you do need to be aware that the water line doesn't reach the intake grid.
What was you other question... well yes, it's the output hose/assembly where the priming suction needs to occur and it's most easily done by disconnecting the spraybar (the spraybar should have suction cups to still hold it in place independently, just slide it sideways in those clips a bit and the output pipe will be handy. I always leave it disconnected from the spraybar while I'm getting the last of the air bubbles out of the system, since it might need a re-prime during this process on rare occasions.

ps. Raptor, WoW, an extra step! Filtering some old tank water through floss. What do you use as your "filter funnel?" This process would certainly carry the advantage of giving your bacteria safe water in case you got distracted during the period between the cleaning and the filter refill (if left till back at the tank.)
