To solve you first question, in the admin product update page, just make sure you select the Puppets and Stage Puppets, so clicking the Puppets category will show all categories.
For your second question, the left navigation is done dynamically and the color is being applied dynamically. so to change those colors, look in the main template and if you look around line 165 you could see that colors you need to change.
Let me know if you still have any other questions.
