Poll: First accessory to buy

I chose flash.

Using filters depends on whether you need the sealing.
Until you have multiple lenses, the case/backpack isn't necessary, and you aren't likely go get the right one until you know what you'll be putting in it.
Tripod depends on what you're shooting.
External hard disk... I don't have any. I have several internal ones. Useful if you use a laptop and want to move files from the camera temporarily before going to your main editing PC. But, yes, in general, you'll want storage. Lots and lots of storage.

More common basics would be:

Memory card.
Optionally a card reader.
Your brain 1*. Learn how the camera works, what the modes are, and how aperture, shutter, and ISO are connected.
Your brain 2*. Learn to compose a shot. Learn about harsh light, and open shade, etc. Figure out what you like, and why.
Second battery.
Lens cleaning supplies (lens pens, microfiber cloth and lens cleaning solution, etc.).
If you purchased a Nikon, something to process .NEF files. Canon users can use DPP.


* - Note that while you don't have to purchase your brain, it's a good thing to invest in.

It's not just about the storage space. Unless you're using an online backup solution (Carbonite/Mozy/etc.) you should always have your image library backed up to at least one external drive (hard drives fail), and ideally in more than one physical location (no one wants to think their house will burn down, but it happens).

Upgrades might be available. I guess I'm the one to see about that...
