As a rule of thumb, the best speaker stands keep the speaker from moving about without causing any additional resonances. (A hollow MDF box may actually make things worse - try filling it with sand or a mixture of concrete and vermiculite.)
While there are many tricks for this, a really heavy stand will often work the best. The sheer mass of the stand alone will damp much of the vibration. This is why cinderblocks work so well.
I rather like the design of the "TNT Stubby" - it's cheap, it's easy to build, and because it's filled with sand, it should work very well indeed. I'm building a pair myself.TNT-Stubby - A DIY Speaker Stand Project on TNT-Audio [English]

Yes, Yes, and very yes.
I've been learning to design speakers, and there is one aspect I've noticed to many designs: While they'll sound just fine if you're up to thirty degrees off to the left or right of the speaker, they'll go completely wonky if you're only ten degrees above or below the plane of the tweeter's output. In other words, head level is the way to go.
Secondly, quite a lot of unnatural-sounding noise is caused by the box itself, which can resonate like a bell. If you can feel a speaker's box buzzing quite strongly even at low volume, it's likely not rigid or well-braced enough. Bowers & Wilikins and Wilson Audio have gone to great lengths to eliminate cabinet resonance, and their work shows.
