display cats AND subcats in shop.browse / display prods with children/attributes

[notdan]

Hi,

i'm looking for someone who's able to do 2 things:

1.
when clicking on a cat in mod_product categories, all the subcats and subsubcats have to be displayed on the website:

clicking on "cat a" in navigation, let's say "xomputers" =>

category childlist.tpl.php shows the following:
subcat 1a (desktop computers)
    subsubcat 1 1a (windows)
    subsubcat 2 1a (mac)
subcat 2a (...)
subcat 3a (laptops)
    subsubcat 1 3a (win)
    subsubcat 2 3a (mac)
...

-------------
2. category browse page has to display add-to-cart-buttons for all the products, also if they have children/attributes (in this case with the opportunity to choose)


cats and subcats (and subsubcats) have to be displayed on shop.browse

-------------

I tryed some solutions, they almost worked, but probably they have to be adopted to vm 1.1.5.

Pls let me know if you can help me and want to come to business.

Thanks,
Daniel
