Yes, you can do this.
There are a couple of ways to approach it depending on exactly what you want to do.
Some elements can be controlled by the stylesheet, so that the information box is not displayed when on a product info page, for example.
To distinguish between categories, you will need to add some code to get the value of the $cPath variable and execute different statements based on that.
We can give more specific advice if you post an example of exactly what you want to do.
If you want very different layouts on different kinds of pages, you can have per-page stylesheets and other files... but this is not likely to be applicable to different categories.
