making notes like this

This may help: https://musescore.org/en/handbook/voices

You mean https://musescore.org/en/handbook/cross-staff-notation ?

I think https://musescore.org/en/handbook/cross-staff-notation would also be helpful for moving the chords from one staff to another. I would put the whole notes in voice 2 and everything else in voice 1. The squiggly lines can be entered as slurs. You will need to select a note on one end of the slur and ctrl+click the note on the other end of the slur. Once entered, you can double click the slur (or click and press ctrl+e) to put the slur in edit mode and move the squares around until they look right to you.

I will make a sample but it will take a little bit of time.

Edit: sample of first measure showing my artistic ability attached.
