I cleaned my filter yesterday and reassembled it seemingly successfully. The I noticed the DEX2400CR GENUINE Hayward Pro-Grid Filter Flex Air Relief was left off by mistake. How critical is it to run the filter with this air relief plug? I assume it's just open now. I am going to reassemble the filter again next week to replace the retaining bolt (mine disintegrated and a new one on order). Can I safely leave it running without the air relief for 3-4 days? I am about to pour in chlorine and shock the pool as part of the start-up.

You can leave it off, but you will find that DE will be in the pool at each start up and may continue to be drawn to the port the tube should be in while the pump is running. The filter will not filter as you would be amazed at how much dirt will just bypass the grids and flow out the port that tube belongs in and back to the pool. Essentially, what you have now is a hole in the filter that blocks nothing.
In other words, "bite the bullet" and put it in place before running the system.
 
I went to put it back on and it looks to me like it was broken off. I reattached the filter with the rod hanging down, which is how it was. But I suspect it is all supposed to be one piece. Hopefully this will at least be an improvement as the filter is clamped on. I ordered a replacement as well. Photo shows the two pieces.

What "rod hanging down" are you taking about? If the stainless through rod that holds the whole grid assembly together, it is supposed to have a nut and washer at the bottom spreader and wing nut and washer at the top so the whole assembly can be taken apart and then held together by that long rod that is threaded at each end. it doesn't just hang down.
For now, you can take that broken part out of the manifold and install the part with the sock into the manifold. The sock should be held on with a clamp.
