I will just share, that it depends on what product you are shooting.
Food has different requirements than small products, then medium sized, from cars. Apparel often needs models who can make the product look good.
For small products by themselves, I use a plain white background with a LED ring light, sometimes with an LED side light, and then a 24mm or 50mm lens just because of the space I have to work in.
I know someone else that has a specifically designed photo box for products, that has soft box equivalent lighting built in. Just turn it on, put the product in and take the picture. Good for objects less than 6" in size in his case. I have seen larger versions.
For products on models, I use exactly the same setup I would for just taking pictures of the models themselves, although the center of attention of the image is on the product, not the model and compose and set lighting appropriately.
Hope that helps someone, but can't get more specific without knowing what products.
And I am with Asher in that those already look like good product shots.
