You seem to be in good shape, everything seems to be working. One issue you may have, which I encountered with a very similar system when upgrading to Windows 8, is that the touchpad disable/enable button between F12 and Insert may not work. This requires a specific touchpad driver which is not compatible with Windows 8.
I do have Dell QuickSet installed on my Inspiron 1564 with similar buttons on the keyboard. Volume, Media, Wireless, Display Mode, Brightness, and Battery buttons all work and work with the Windows 8 built in functionality (on screen volume display, Windows 8 display mode options, etc.). The version I have installed is 9.6.21.
It would seem that despite the official compatibility information, the N5030 is compatible with Windows 8.
