Magento Product View layout (bootstrap responsive)

https://goldenfreshasiangrocery.com.au/index.php/grocery-frozen.html

1) I need to update product listing layout. 5 products per row for desktop, 3 products per row for ipad, 2 products per row for mobile.

2) On top of the product listing page, I would like to add "filter by category" and sort by. e.g website. (https://springvale.kflsupermarket.com.au/en/collections/%E4%B8%AD%E5%BC%8F%E4%BA%A7%E5%93%81-chinese-grocery )

3) In product view page (https://goldenfreshasiangrocery.com.au/index.php/del-monte-moroccan-style-vegetable-pot.html) I would like to remove some (such au my cart, newsletter etc) and would like to keep simple.
