1) Not canon.
2) It's Ben Skywalker, not Solo. Ben is Luke's son
3) Leia and Han's children are Jacen, Anakin, Titus, and Jaina. Anakin dies. Can't remember what happened to Titus
4) Jacen becomes a Sith, kills Mara Jade, Luke's wife and briefly takes Ben as his apprentice
5) Due to Luke's adamant belief in redemption, Ben leaves Jacen/Darth Caedus' side
6) Darth Caedus is turned back to the light side by his twin sister Jaina.
7) Han and Leia are barely involved in the EU, except when Luke turns to the Dark Side briefly
I've never read anything in the extended universe. Not to mention that the extended universe is, as you said, not canon. Episode VII, the Force Awakens is. For the record, everything I said that was spoiler-y, was in a spoiler tag.
[spoiler]1) Who tf are all these solos? Sounds like Leia and Han were really going at it.
2) Family Feud to the extreme: that's now star wars.[/spoiler]
