Replace a Module with a Class and Shared Member Question

[BukHix]

I want to replace the Public Declarations that I currently store in a Module with a Class.

Currently in my Module I have a declaration like this:

Public SetPath As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments

How do I get the same functionality from a Class?

Public Class Audits

    Private _SetPath As String
    Public Property SetPath() As String
        Get
            Return _SetPath
        End Get
        Set(ByVal value As String)
            _SetPath = value
        End Set
    End Property

End Class

I know I can reference the SetPath in code by doing a Dim aud as New Audit so my question is this. Where is the correct place to put the

= My.Computer.FileSystem.SpecialDirectories.MyDocuments

And is this an good example of a member that should be shared? If so does both the Private and the Public need to be shared. I just started using Refactor Pro and it almost always is recommending that I make all members shared. Is there ever a good reason not to do so?
