Some questions about Amazon Affiliate

Hi everyone i'm new to BHW and the internet marketing area in general - nice to meet you!
I've been reading many threads lately on the forums and now I have decided I want to adventure into Amazon Affiliate program by creating a blog.
I want to ask some (probably stupid) questions about this, I'd really appreciate if someone could help me out
1. I live in italy, do I have to sell only Italian products to italian people or I can also sell US/UK products to their respective countries?
2. My idea is that in my blog I write articles like "Top10 cameras in late 2019" where I review 10 camers and then add a "BUY NOW" option with the ref link. Is this the correct way?
3. I have no knoweledge outside my areas of expertise (programming and music), how would I be able to write some good content, keeping in mind that I'm also not a native speaker? Do I have to google other articles and re-write what they've written?
4. Where can I learn about SEO stuff from the very basics and up? I keep seeing many acronyms on the forums that I often don't understand :\

Welcome to BHW. Glad to have you and it's nice to see that you've been doing some research. Thing is, indeed, all of these questions have answers on the forum, and the more time you spend researching here, the better off you will be on your journey, but here is a basic starting point for you:

There aren't geo restrictions. You can sell products worldwide within the framework and regulations of the Amazon Aff program.

There are lots of ways to incorporate Amazon affiliate marketing within a blog, but product reviews and niche sites are certainly two of the most viable.

If English is a challenge for you, rewriting other articles into a fluid context may be a far reach. There are plenty of great content writers here, e.g. @ContentExpert @Meddie

You can sell products to any country, you do not need to live there. For example, I opened Amazon affiliate accounts with UK, US and Canada as I get traffic from those locations and want to maximise sales from my sites. Some sites I have with content specific to the UK, others with content aimed at the US & Canada, others aimed globally. I am likely to get an Australian affiliate account in the near future as I am getting quite a bit of traffic from a couple of sites now.

Basically, you can sell products via affiliate links in any country that you can get someone to click and buy a product.

Absolutely correct. I also add the link to images and product titles personally.

Read about the products you are going to sell and create articles based on the knowledge you build up, so you can answer questions that your readers might have. But you can also re-write others articles.

Look at the green sticky threads in the White Hat SEO forum, there are some easy to follow guides which give you the basics.

Best of luck with the sites, just remember that it takes time with Google to get anywhere, so expect a number of months. However, you can use things like social media and Reddit + other forums to get sales quicker.
