Not in all ports. Some ports, libraries in particular, can often be installed with support for both X11 and Quartz graphics.

No, +quartz uses OS X's native Quartz graphics:
+x11 uses X11 graphics:
The "XQuartz" project is an unfortunately-named package. It is a collection of X11 software built for OS X. It provides an X11 interface for OS X. Programs communicate with XQuartz using the X11 interface, not the Quartz interface. (The Quartz interface is built into OS X and no other libraries are required to use it beyond those that come with OS X.)

XQuartz has its own versioning scheme. "2.7.4" only tells you the version number of that particular XQuartz collection. It does not tell you the version number of quartz-wm or any of the hundreds of other parts of the X11 system contained within XQuartz.
Apple used to include X11 in OS X. The way they did so was to include the then-current version of XQuartz in OS X. But Apple seldom updated this throughout the life of a version of OS X so it became out of date. Users could elect to update their X11 manually by installing a newer version of XQuartz. Now, Apple has removed X11 from OS X, so if you want X11 at all, and are not using MacPorts, you must install XQuartz. This ensures you'll get a current version and not an old one.
If you are using MacPorts, then installing the xorg ports is probably better, since it keeps more of your software in the MacPorts system (one place to update all your software), and it's probably more up to date than XQuartz, since each component is updated in MacPorts when it's ready, instead of having to bundle them all into a single distribution. The XQuartz package and the xorg ports in MacPorts are maintained by the same person at Apple so they are the same software.
