If you haven't already done so, you might want to e-mail these questions to Outlaw (info@outlawaudio.com) -- they are probably the only ones who can answer most of those questions for you, and while they monitor the forum they don't routinely post here. From what I can tell from here , though, the bottom of the all-black stands is MDF, the center pillar is extruded aluminum, and I don't see any indication of the stands being provided with casters (they have spikes or feet, both adjustable, and I suspect but can't guarantee that the dimensions listed do not include them, so you might want to add half an inch or so for spikes/feet). If you do contact Outlaw, let us know what you find out.
