For the first one you need to add your own MachineKey.For example:

<machineKey validationKey="DBAEF98E532D4161826F8351C794DFD27C0F814262FD6986"
          decryptionKey="DBAEF98E532D4161826F8351C794DFD27C0F814262FD6986"
          validation="SHA1" decryption="AES" />

within section of your web.config file.You can use this site to create your own validationkey.

For the second one check with your hosting company and see if they use any specific settings.Yours look fine to me.
