Hey man,
That trim on top of the windshield and back window is tricky. Any of the local auto parts stores should carry a window trim removal tool that looks like this

use the hook on the tool to pry under the edge of the trim and pop the clips loose.

the trim piece around the doors should be retained by plastic clips and can be pryed out by working under them at one end with a thin screwdriver and pop the clips out of their holes. Thats how those pieces came apart on my accord, and Honda is pretty good about maintaining uniformity among model lines. If you can get your hands on a shop manual for the car, it will have detailed illustrations on how to take it apart.

Hope that helps,
