learning X programming

I have the following documents:

(1) Xlib - C Language X Interface
X Consortium Standard
X Version 11, Release 6.4
(2) X Toolkit Intrinsics -- C Language Interface
X Window System
X Version 11, Release 6.4
First Revision - April 1994

The former is 466 pages, the latter about 291 pages. Which of them
should I read first?

If there is something I should read before either of them, which is
probably likely, that would be good to know. Also, neither of them
seems to spend any time on programming examples. A source that shows
how to get started with X programming under Linux would also be welcome.

Most likely I would be doing this in C, but I also have my eye on the
following document:
(3) Xlibscm
SCM Language X Interface
Version 5d8
