Forst of all both things are nothing that requires a change in the patch
itself.  

1: That's a matter of displaying the topology.  You can use a separate
MechSim_Show_Objects() for each group and texture them differently:

#declare Obj1=MechSim_Show_Objects(...)

object {
  Obj1
  texture { ... }
}

MechSim_Show_Patch() would work alike.

2: There are two possible ways of smoothing a mesh in such a case.  You
can either use a threshold for the angle between the faces to determine
whether to smooth the normal vectors or for a rectangular grid you can of
course determine from the node index if the normals should be smoothed. 
Both things can be implemented in macros.

You have to link them exactly how they are linked internally, i.e. create
connections between adjacent masses.  

The cranes you can see on my website are not created with the same system
but essentially the interconnections are created one by one manually.
