Big congrats to you, @crypto.piotr. My advice is to call us STEEM since steemit is only one of the dApps; and about the worst one for new people to start with to boot.
I have all kinds of information in the mega-minnow tips post. Delegating SP and the other topics you mention having trouble with are explained in some of the many links.
