I\'m trying to find IBM Worklight Studio v5.0.0.3 (Eclipse plug-in).
The Eclipse Marketplace provides only the latest version (5.0.6).
It seems that IBM does not
The eclipse marketplace version is the free Developer Edition. It runs completely within eclipse and there's no standalone Worklight server.
If you've install a separate Worklight server (on Liberty, WAS, or Tomcat) then you're running the Worklight Consumer or Worklight Enterprise edition and should use the studio plugin for that edition/version. As Idan mentioned, Business Partners can get the corresponding studio plugin from PartnerWorld.
You say you have Worklight Server installed but not Worklight Studio, this implies to me that you are either a customer or partner of IBM (and have installed Worklight using the IBM Installation Manager).
Worklight Developer Edition installation:
1.Eclipse Juno 4.2.2 (Java Platform, Enterprise Edition, or Classic). The Worklight installation will fail if you are running a different version of Eclipse
Note: Java Platform Eclipse will be preferable. Download Link : http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/juno/SR2/eclipse-java-juno-SR2-win32-x86_64.zip
2.Supported operating systems: Mac OS X Lion 10.7 or Mountain Lion 10.8; Windows 7 or 8; Linux Red Hat Workstation 6, Linux SUSE 11, or Ubuntu 12.04

Save your time installing 5.0.3 especially if you are planning on using jQuery that comes with worklight native. 5.0.6 comes with 1.8.2 jQuery and has better native calls for worklight to save you time when you need to get usefull info and use the enhanced logging properties.
Trust me. If you you are not going to wait until 6.0 the use 5.0.6 and save yourself a lot of UI headaches.
