I had them done at Fender Mender in Mount Pleasant, SC.
I did not have to re-program the unlock button on the door handle.
The window trim pieces I am referring to are the ones at the bottom of the sill only. They are chrome plated on the LX and were not on LCs at least in 2008 and 2009.
See arrows.

I do not have the part numbers. What I did was gave them the VIN from a 2008 LC and had them pull up a diagram and find the parts.
They probably still have the file under my name. I am pretty sure they would. It was done in 2012.
Frankly, you can replace each of the window pieces in probably 10 seconds by yourself. The old ones just pull up (pull carefully) and come off. The new ones just pop into place. They are not expensive at all.
PM me if you want my email or cell to help you out.
