I took my reservoir and everything else apart last week to find out where my mystery leak was coming from. Like you, I also found that circular top strainer laying on the bottom of the reservoir. The tabs around its perimeter were very flimsy, so I don't see a need to replace it because it'll just fall inside again after time.
I didn't see the blue part you listed. Those are not the 2 oem strainer grommets that attach on the bottom of the washer pumps. The oem strainers are also vented on the sides. Very odd.
