I see many people in this forum discussing the manager templates, I also want to have a look on it, but I cannot find where is it... could anyone show me where can I get it? Thank you very much!

There might be an easier way, but you can definitely check them out of the svn repository

svn://www.sd.nl/LLBLGenPro/Templates

If you don't have a subversion client, TortoiseSVN is easy to use http://tortoisesvn.tigris.org/download.html
