How to get certain product data in tpl - custom category pages

[belwarg]

Hello!
I want to change category pages for some of categories in my shop.

How it will work:
- for some categories (based on category id) display custom template
- for rest of categories display default category page.

For my choosen categories i want display category title, description, and some product data (of course all products will be in that category). 

Question is - can I type something like <h1>{$product->name|escape:'htmlall':'UTF-8', X}</h1> where X is id of existing product?

After category description I want to display 6 products, I know them ids, all I need is just to display their data (name, image, price, description) - only for these 6 products, not for every product in category.

CategoryController.php, depending on category id load different template files (in initContent function),

you can do it with if conditions (if category == 1 elseif category ==2 etc.) or with switch (proper method) function
