Need help with Sach Kit installation

[Badkrma]

I have done several searches and did not see it ask or answered. I have a 1990 535 with an automatic if that makes a difference.

1. On the front struts, do I need to fill tube with oil as per the repair manual?

2. What do I do for the rear bump stops? I have an email into Sachs, but I am starting the project.

Also,

When doing the upper and lower Thrust/control arms, did any of you put the 150 lbs in both front seats and 150 lbs in the center of the rear seat before finishing tightening the bolts?

Thank you.
