I would actually recommend going for a Lee Filter System and their 10 stop "Lee Big Stopper" as it's much easier to control / use along with graduated neutral density filters. As the B+W is a screw on filter, you need to 'guess' where to put a grad filter (if you can) where as with the Lee system you can line up a grad filter then slip in the big stopper. Additionally, the colour cast of the Lee Big Stopper is easier to correct than the magenta cast of the B+W.
With regards to exposure time, I generally just guess it; I've got enough experience with long exposures to get pretty close by judging the light level by eye and then firing off a shot. If I find that I've underexposed by half a stop to one stop, then I will make the aperture bigger (I usually start at f/11 to give me headroom to come down to f/8) and take it again for roughly the same time. If i'm already at f/8, then I may need to double up the exposure time, so if I took a shot at f/8 and found it underexposed by a stop after 60 seconds, I will take it again but run it for 120 seconds.
As most of my landscapes are around 10mm to 12mm, f/8 still gives plenty DoF and keeps the Sigma in the sweet spot for sharpness.

Yes, at 10mm with NDs you can lose some light around the edges, but it's only slightly and you can correct peripheral illumincation in Camera Raw quite easily.

If you want rectilinear wide angle with distortion correction whilst taking the shot, then it's over to tilt and shift lenses; I reallllllllly want the Canon EF TS-E 17mm on a full frame body, take a look at the group on Flickr:

Those verticals are damn perfect (where used properly).

Would the f/3.5 version really make that much of a difference though? What sort of situations are you shooting with it?
