Looking for worksheet templates

I’m looking for sample templates, worksheets etc to assist me with the documentation of help desk issues.

The product we support is very new as is the help desk, and at the moment I am compiling any issues we come across on a very simple excel sheet. However as time goes by I will need some things more complex for the purposes of:
– recording new issues that arise
– archiving existing issues
– spreadsheets that can link together information

I’m not after tutorials on how to do this, rather just samples of what people use – from a second/third level help desk/call centre point of view – preferrably in MS Office products, or Sharepoint.
