And while I fiddle with this thing, is there any way to get the live CD installer to work with these drives without poking around with some other OS to partition the drive? In my rather limited experience, dedicating two 2TB drives to the rpool for a home server is rather a waste. I have mirrored 500GB drives on mine and they are a vast wasteland of unused capacity. In my opinion you could go even smaller if you could put the money to better use. The raid-z vs mirrors question can quickly get rather complicated. I'd say if you think 4TB is going to hold you for a good long while, then go with mirrors. If the six drives you're already talking about are going to stretch the capacity of your case and you think you may need to expand beyond 4TB in the reasonably near future, then you might want to consider raid-z1 to get 6TB usable space from your data pool.
