New user, needs guidance

[Doopz]

As I continue to learn PrestaShop, there are questions I hope someone has answers to! So I'll start with these.. I'm running a site in Catalog mode using

1. How can I disable the availability, condition and price range bar in the enabled filter (left-side) panel?
2. Is there any way to still have a Wishlist in catalog mode?
3. Any way to showcase New categories, or subcategories instead of New Products?
4. Currently using the Categories block however I'm unsure where to change the thumbnail size for this. Which is also leaving an unwanted black border.
5. Is there any way to change the color of the product box hover effect?

Any guidance would be appreciated!
