Protecting Worksheet But Only Cells

I have a spreadsheet with about 2000 lines of vba code. My application needs to be protected so users don't mess themselves up; however, I really only needs the contents of cells to be protected. I have many macros that run, and in order to do this I need to unprotect and re-protect the worksheets. My problem is this: when I re-protect the worksheets, everything is locked up. I would like to allow users to change column widths, hide and un-hide rows, etc. I can't find the parameters needed to do this more controlled type of locking. Is there a list somewhere of all the parameters that can be passed to the Protect method? Here is my current subroutine:

Sub ProtectSheets()
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
ws.Protect Password:="password"
Next
End Sub
