How does a quark that lives as short a time span as the Top, interact with a Higgs Boson? Also – if a particle is made that is larger than a Top Quark, is it a quark, a boson or something different? To me it seems the T is more a boson than a quark….

The class a particle belongs to is defined by its spin (quark’s spin ½, boson’s spin 0,1,2…) and electrical charge, because these are the numbers that define the symmetry properties of a particle, not their mass. So I guess if a more massive particle turned out, what it is would depend on its spin and charge. 

I don’t know enough about the Higgs boson to answer your first question, but maybe this could help you?
