Just thought I'd finish this up for anyone using the search function to find the answer.
I dealt with the 9 trim pieces by sticking a screwdriver (wrapped in black electrical tape) in the opening on the bottom of the panel. Once I loosened that first clip I took out the rest by prying the panel piece (along its perimeter) with my hand. Once you do this look back into the manual for the rest of the steps (

Also, I solved the metallic rattle by tighteninga bolt, and a plastic rattle, on the other door, by tightening the screws that hold the power window & lock setup.
