I would be more gentle than just ripping on things like what's shown in that install video. These are plastics you're pulling on, not suspension components.
Good tip I heard from a pro; if you're working on the interior, it's best to do it on a hot day or when the interior is warmed up. That way the plastics are warm and have greater flexibility. In cold weather, there's a greater chance of breaking a plastic clip because they are in a more 'solid' state, if you will.
Also, if you have a 4WD and it's '01+, you can't just unscrew the 4WD selector knob (unless yours is '96-'00) like the video states. There is a small black screw that holds onto it and a wire connector underneath the boot, so be mindful of that when removing the lower shifter surround.
