I haven't played much with 'digital' ND grad effects, but I agree with those that say once you blow the highlights, you can't recover them. If you're at that point, you're going to have to merge images or mess with HDR. I think your investment is a good one for landscape.
One of the most popular HDR software programs is Photomatix. There is a demo version for you to download and experiment with. Also, know that it has a 'ghost removal' tool, so you can highlight areas of movement; it's limited as I recall, I think it chooses one of the 3 moving images for you. I haven't investigated it much though.
I agree, it takes a bit of effort to make HDR's natural-looking, but it can be done.
FYI, I have the Singh-Ray Vari-ND. It can cause vignetting at the wide side of some WA lenses, especially the wide of of my 10-22 EF-S, my most-used lens. Also, I've found I get blotchy spots when I crank up the filter to around 8 stops, and from googling, that seems universal. So if you get one, just know you probably will actually have around 7 usable stops, +/- I still like it, much easier than carrying around several different ND filters and screwing them on/off. They do make a thin ring mount version; I don't think it has threads so you can put a standard lens cap or any more filters in front of it.
You may also run into vigentting with Lees Filter holders/Cokin holders with wide angle lenses, although there are wide-angle versions of both (some take a hack-saw to the Cokin holder).
You mentioned using Vari-ND and circular polarizers. Well, I was shooting a waterfall with the Vari-ND, and noticed a bit of a rainbow showing up. I slapped on a Singh-Ray circular polarizer. While I was adjusting, I accidentally turned the Vari-ND to its max and got an interesting effect. This is with no adjustment beyond resizing for upload.
