Yes... but you also said you installed XFree86 and Xorg, which are two additional ways X11 gets onto your system.

Right, on Mac OS X, X11 is a secondary windowing system you can run when needed.

Is X11.app in the dock and open? If yes, it's running. If no, it's not.

Apple's X11 provided on the install DVD installs into /usr/X11. The XFree86 port in MacPorts appears to install into the same place. (Note it is not usual for ports to install outside of the MacPorts prefix.) The xorg ports install into the MacPorts prefix.

Yes. "man launchd" has more.

Apple X11 was based on XFree86 in Mac OS X 10.4 and earlier, but in Mac OS X 10.5 and later it is based on xorg.

Correct. Or, if you installed the xorg MacPorts port, then X11.app is in /Applications/MacPorts.

It's not expected for you to have to run startx manually. Just open X11.app when you want to use X11.

You have a libtiff.dylib (or libTIFF.dylib) somewhere that is not built properly.

Apple's libraries are properly integrated but you have destroyed that integration by setting DYLD_LIBRARY_PATH and similar variables.
