Can I cap and abandon this old cast drain pipe?

We are adding a shower to the basement bathroom and thought the pipe going to the toilet and sink was updated with the rest of the pipes. It wasn't and runs parallel to the new abs which goes to the main stack and upstairs toilet. The cast must connect to the abs somewhere to the left, as I know it's ABS further down the line and where it exits the house. Can I cap and abandon the old cast next to the cleanout and continue the new abs to the right and connect the basement toilet, shower and sink to the ABS? TIA

Should I remove the plate behind the black mixer cup?

The top screw (encircled in blue) is stripped. Before I go in there with drill bits and screw extractors and ATTEMPT to remvoe the broken off screw, I was wondering if I could easily remove the black mixer cup and the plate behind it (encircled in red). Removing this plate would give me better access to the screw. And if in fact, the plate can be easily removed by unscrewing the two large screws, do I need to shut the water off prior to doing this? I am just a home owner DIY'ing, with limited plumbing knowledge, so any pointers would help. Thanks! Note: The screw was stripped by the previous home owner

Submersible sewage pump, fall on send pipe?

Does the Send line to the septic tank need fall like normal plumbing? I'm wondering if I can get away with running with minimal fall because it's pumping and not relying on gravity. I'm in Ontario, Canada.
