This first sentence in your first bullet is a note, not a step, and iFixit has a special bullet to denote notes. Use that.

Include the screw length in what will now be your second bullet.

Your current second bullet should be formatted as a warning —- again the iFixit wiki enables this.

How does the user remove the fan?

Make the second sentence a second bullet.

Use the internal markup tools to indicate small components, like screws.

Again, how should this be slid?

Perhaps a note here that indicates that the two components of the part will remain connected after they are gently separated?

Same as in previous guide — retake images using the proper tool and rewrite the associated step accordingly (without “it is recommended”).
