Answer 1

VS2008 is using your credentials when executing web application. You will need to set up an account (one that has access to the remote folder) in your IIS virtual directory.

Answer 2

you'll need to set the Application Pool's Identity to a domain account (domain\user) with access to this shared folder, the built-in "Network Service" account doesn't have access to a remote shared folder.

To change your App Pool Identity:

you'll need to know which Application Pool your website is using by going to the Website properties "Home Directory" tab (Application Pool is the last item)

Close out the Website properties and under Application Pools in IIS find the corresponding Application Pool, open properties and go to the "Identity" tab to change the user.

You need to chmod the shared folder so it is readable and writable to you and/or others. Usually the host has an interface for this. As far as I know, the permissions cannot be set from code.
