I'm sure you'll probably have realized by now, but I found the most important addition to my DSLR bag when I started out was a spare battery and SD card. It's quite humiliating going on a nice walk thinking I've got half a battery left that will be plenty then at the end of the walk having your other half say 'that's an amazing view can I just take a photo of it' and discovering you've just used up the last of the battery/SD card.

If your going through a proxy server you might want to check you have Microsoft's activation URL's unblocked (or depending on your filtering system which ever category is the most permissive and if possible doesn't use any authentication). http://support.microsoft.com/kb/921471/en-us
