I seem to get a Cannot access a disposed object error if I dispose the icon
directly off the notifyicon control... any ways around this?

If you create it, and can Dispose of it when you're done with it, then do
so.

ntfIcon.Icon = New Icon(Icon.FromHandle(bmp.GetHicon), New Size(16, 16))

GDI objects tend to wrap up Unmanaged resources and, if you don't
explicitly Dispose of them, they'll hang around, holding onto those
precious resources, until Garbage Collection [finally] gets around to
clearing them up; which /might/ not be for hours!

Try something like this:

Dim icon as New Icon( ...

If Not ( ntfIcon Is Nothing ) Then
ntfIcon.Dispose()
ntfIcon = icon
End If
