When I start CMD, I see C:\Users\dave> but I want to change directory to C:\wamp\www without having to press cd ../../. So I created a shortcut of the 'www' folder in the 'dave' folder.
This is a typical X-Y problem. If you want CMD to always open at a specific directory instead of the default, all you need to do is simply change the shortcut's properties as follows:

In Windows 7 the Command Prompt shortcut is typically located in Start Menu > All Programs > Accessories
, so just right-click the shortcut, select Properties and edit the Start in field to your liking.
You can also create a batch file named for example d.bat that contains a single line cd /d c:\wamp\www
. Place the batch file somewhere in your path and now all you need to do is open CMD and type d to change to the specific directory. There are many more similar solutions as well.
If you are dead set on parsing a shortcut (.LNK) file from the command prompt, save the following as ParseLnk.bat and execute it from the Command Prompt as ParseLnk <LNK File>
:
@echo off
echo set WshShell = WScript.CreateObject("WScript.Shell")>Tmp.vbs
echo set Lnk = WshShell.Createshortcut(WScript.Arguments(0))>>Tmp.vbs
echo WScript.Echo Lnk.TargetPath>>Tmp.vbs
for /f "delims=" %%d in ('cscript //nologo Tmp.vbs "%~1"') do del Tmp.vbs & cd /d "%%d"
cmd /K "cd /d C:\Folder\Folder
will open CMD in C:\Folder\Folder
