I was lucky enough to get my D800 yesterday, and now I'm looking for a "best practice" solution to downsample the raw (NEF) images that I import into Lightroom from my D800. My normal workflow is to import and backup the NEF images from my DSLR, and only create PSD copies for those photos that merit retouching. I find the D800 photos are roughly 2.5 times larger than the ones from my D7000, and I don't always need the extra resolution. Often I'd just like to downsample the D800 images to get better S/N and save space on my hard drives. Has anyone found a good way to do this?

I don't have a D800 yet, but playing with some posted D800 RAW files I downsampled by resizing (and resampling) from within Capture NX 2: Edit -> Size/REsolution. (Ensure 'Resample Image' is selected) Choose your output size or file size and click on apply.)
I have used this method on RAW images from my D300 for years to both upsample and downsample. (I do this at the end of work-flow, just before output sharpening.)
Ok, I just re-read what you posted. What I suggested will work for changing the size of an output jpeg but won't change much of the size of your NEF file: Capture NX 2 is non-destructive, the original raw data is still in the NEF file.

As you can't res NEFs down, I'm presuming you're only talking about the images that you're taking into a PSD format. Given that, just 1) resize the images using LR4's export panel before taking them into Photoshop or 2) resize them using the bicubic sharper option in Photoshop once you've pulled them into CS5. You could also save your completed work as 8-bit PSDs, which would halve the space required on your drives if you're not already doing that. Personally, I would never do this given how inexpensive large hard drives are. I'd also make certain I was taking advantage of every single editing option LR offers first (and there are many in LR4) so that I could stay with the smaller-sized raw files.
