Which of the social plugins above really affects SEO - Why and How?

None of them help you with SEO and that's ok because that's not the point of them. They're they're to help you promote your website, they're not SEO tools.

Is it enough to put an anchor link to the page in the social network (facebook.com/page, twitter.com/page ...) or do I really need the +1 and Like button? - I know that lazy people like to click as little as possible, but do they really click without to see the page itself before?

If you want the +1 and Like functionality to work you'll need to use whatever methods are available for each. If they offer plain text links to count +1's and Likes then you can use them. Otherwise you'll need to use the buttons. Keep in mind that users are more familiar with the buttons then not so if you deviate from this you better make it as intuitive as possible or likely see a reduced number of clicks.
