If you're going to read just one Pern-themed book, try McCaffrey's
Moreta, which gives the broadest picture of Pernese life and is a great
tale to boot; otherwise, enjoy the first two trilogies: Dragonflight
(the first to be written of all the books, and wonderfully dramatic),
Dragonquest, The White Dragon focusing on Weyr life (and)
Dragonsinger, Dragondrums which primarily explore the Harper Hall.
As for other books, The Dragonlover's Guide to Pern written by Jody
Lynne Nye with Anne McCaffrey provides quite a lot of information, and
even a short story. Note that in some cases info differs between books
written earlier and books written later. The People of Pern by Robin
Wood displays some paintings of McCaffrey's characters, and even--on the
cover--an image of McCaffrey herself!
Nerilka's Story is set around the same time as
Moreta and includes a
Hold marriage, among other things. Later books such as All the Weyrs of
Pern and Dolphins of Pern are interesting reading, but don't apply to DF
Pern as directly; Dragonsfire is set two Intervals after the one in
which Dragonflight began, but began before AtWoP was published and thus
its timeline diverges strongly at that point, with no AIVAS. Books set
earlier in time such as Dragonsdawn and Dragonseye (aka Red Star Rising)
likewise don't directly apply, as even in Moreta's time Pernese had
forgotten their origins. However, for example, Chronicles of Pern: First
Fall gives helpful information on flying Thread when one is pregnant.
