New to Lord of the Rings

Thank you guys, I appreciate your responses. I'll post my questions as soon as I can, but for now I would just like to know what edition of books do you all have and wich you like the most. I know there are a lot of editions in english, but here in México there's only two: the three separated books on paperback edition with paintings from John Howe on the cover(Gandalf on the first, the tower of Isengard on the second and Minas Tirith on the third) and the one volume edition with paintings from Alan Lee, I have both editions but I like better the big one volume edition, it's goregeous and I like how it looks on my bookshelf.
