This depends on what exactly you mean by 'my webcenter'.
If all you want is develop your own webcenter applications (using the WebCenter Framework), you might be good to go only with the webcenter jdev plug-in (see http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/156082.xml#oracle.webcenter.app). Your apps will be deployed to the integrated WLS. There will be two important missing pieces:
a) WebCenter Content as the document storage (requires also a database)
b) BPEL/BPM as the workflow engine
You might also want to install WebCenter Portal: Spaces, or deploy your apps to a separate WebCenter Portal server (running on its own Weblogic Server).
Optionally, you might also want to utilize other servers contained in the WebCenter Portal license such as Secure Enterprise Search for enterprise searching and/or Oracle Access Manager for enabling single sign-on between the above mentioned components.

Installer of what?

If you mean JDev plugin, then no, you need the corresponding version. You can give it a try, though - the system might show you a warning and not continue with the installation.
Thanks very much for your reply. One of the challenge I have now is that am not seeing the installers for 32bit, they's all in 64bit. Is there any link for the 32bit installer.
You can use the generic to install on any version of OS and any System Architecture, use this documentation to know how
Also, can I install Webcenter 188.8.131.52.0 on Jdev 184.108.40.206.0
No, and it's not recommended.
