I believe the answer to question is that the ATP standards apply, even if you are applying for the rating on a CPL
Question 2: You would need to do an actual landing in the plane, if all training is accomplished in the sim. But some training centers/sims have exceptions and you would need to look at them individually. It would be hard, nowadays, to put a TR on a CPL-everything is done to ATP standards and licensing. Just a practical matter CPLs flying type-rated planes is rather rare and limited to Part 91 private operators and, even there, the ATP is effective standard for the last 20 years. It is legally possible, just not done much.
