Which memory cards do I need?

Rob Galbraith has some great benchmarks if you want to know which work best, and at what point it's not really helping while in camera (but still usually faster via good USB3.0 reader to PC).
Rob's site specific already to D800:
I'd stick with name brand media. Sandisk and Lexar are some of my favorites.
I'd recommend the Lexar Pro 600x or 1000x CF cards.
For SD i'd recommend the Sandisk Ultra cards.
Size really depends on budget, but realize that there are speed increases usually for the larger capacity cards vs their smaller capacity versions. (that said the rob galbraith site actually shows a differnece the other direction for the CF Lexar cards! odd, but hey it's minor.)
My Lexar Pro CF benchmarked at over 90MB/s! really like that when importing into Lightroom w/ good reader. Those 40MB files really can use the extra transfer speed!!
HTH - GL!

now that you have some specifics, i'd add that i'd still buy the fastest CF you can afford. 600-1000x recommended.
For SD (where i write video to), minimum Class 10, preferably UHS-1 or stamped as U1 (supposed to be faster than class 10). There are thousands of brands and prices are all over the place. Realize that cheap SD cards stamped w/ "Class 10" or "U1" may not actually perform at that level. Especially beware of those on ebay (lots of knock off and counterfeit cards).
I usually look at amazon as regularly people will post their actual benchmark results (usually in MB/s) to compare with other model/brands you are considering. Very helpful IMO.

Just for some perspective however, full HD video doesn't take anything very special, medium speed cards are fine. video is not much of a challenge for it, the higher speed cards are to empty the buffer of those monster still images faster so burst mode runs a few images longer.
If you plan to use CF and SD both, one backing up the other, note that the buffer empty time is sequential -- it takes the time to write to the CD PLUS the time to write to the SD. So in backup mode it doesn't help (much) to have a super-fast CF and a slow SD.
But in reality it only helps a little to have a super fast card. It still has a pretty small buffer, it adds a few shots to it, but not a lot.
HOWEVER, the images are huge. If you shoot a lot at a time, you can and will fill it up quickly. So my advice is a bit contrary -- unless you like changing cards in the field (something I try never to do), buy BIG before FAST.
I use a 64Gig 60MBs CF card as primary and a pretty slow 45MBs SD card at 128Gig as backup. I often chimp and delete in the field a lot, and since deletes don't remove from the backup, the backup card (in that case) needs to be bigger. Plus I figure if I ever really fill the 64Gig I can turn off backup, turn on overflow, and have another 40-50Gig in a pinch not backed up.
I also have a 1000x Lexar. First one failed in the D800. Made me nervous ever since. So I have tried fast cards, they are faster, absolutely. If money is no object, buy big AND fast. But if money is an object I'd suggest buying BIG first.

I prefer big and fast.
I currently use 128GB Lexar 1000x CFs and 128GB Lexar 600x SDs.
Even though I don't think the camera can write that fast to the 1000x cards, their read speeds are excellent when I'm dumping a thousand pictures to my computer at the end of the day.
I write RAW to the CFs and JPEGs to the SDs. I record video the SD as well.
Overall I find this setup excellent to use.
The JPEGs on a separate card is great for showing pictures on the fly on the many TV and computers have only SD card slots.
And in a pinch I use overflow between the two cards and both are very fast and big. I have one of those memory card backup drives as well to keep a good backup in the field.
