ExcelBanter - Run code for multiple worksheets in a workbook & Column Formatting

The code below looks at a spreadsheet with 8 different reports that all begin with the header "Summary of...". It finds each instance of the word "Summary", copies each report into a new file and then names that file based on the contents of the header and the sheet name. I have 4 questions:
1 - Where/how do I adjust the columns to automatically fit the largest item?
2 - How can I set this up to run for multiple worksheets within the workbook, each worksheet has the same format?
4 - Is there any way that when I copy a cell that has a reference to another cell, that the value of that cell reference is copied, currently I am getting a cell with #ref.
3 - How do I save this so that it can be executed by multiple users - (like a procedure)?

I appreciate all your help!
