Yes, aragonite is a better choice, but more expensive. For a Remote DSB, many people already have an aragonite sand bed in their display tank. Silicate leeching is what may cause diatom and other algae blooms, but this is apparantly somewhat of a myth according to a large thread on RC. I would still monitor using a silicate test kit to be sure.

Very slowly, yes. But you still should suppliment properly (buffers, calc reactor, kalk reactor).
The point of an RDSB is to be a cheap way to hopefully decrease nitrates, but if you can afford aragonite, go for it, it is a better choice for sure.

I have been following the very large thread on RC, and there have been people who have experienced drops in nitrates, and a few people here on CanReef have gotten posative results as well. It takes about 4 weeks or more for those who have seen results.
As for pitfalls: 1. Don't overdue your bulkheads (too much flow) 2. Cover the pail so you minimize algae growth in the bucket 3. Put a larger grain sand on top so your sand doesn't blow around 4. Input water should be pre-filtered so you dont get waste build up in your bucket, skimmer output works well

A remote DSB can also be just be partitioned section in your sump with sand. Get some critters (pods) or macroalgea and your sump is now also a refugium.
You'll probably find that more common, successful and beneficial than a 5g pail full of sand. http://www.wetwebmedia.com/refugium.htm

That would be a bit different, but as long as the sand bed is at least 8" deep you should get the same benefits.
