Blood Status and House Question

I looked up all the  students in Harry's year blood status and a few things 
surprised  me:

1. I only counted 5 muggle-borns
2. I counted 15 purebloods,  since the Patils are twins that means there's 14 
pure blood families:  Weasley, Longbottom, Patil, Brown, Malfoy, Crabbe, 
Goyle, Nott, Zabini,  Parkinson, Greengrass, Cornfoot, McDougal, and 
MacMillan.

So from this  I take it that it's rare to be a muggle-born wizard. But the 
thing that  puzzled me was the large amount of pureblood students, I was 
under 
the  impression that purebloods were rare? I thought most wizards were  
half-blood?

Also, did anyone ever discover who the 6 unidentified  students houses are? 
We can deduct that they're not in Ravenclaw since the  dorm rooms are full 
and 
that the 2 Griffindors must be girls as well as  the one Slytherin.

Another question, does being pureblood automatically  make someone a 
candidate for Slytherin? I've deducted that Slytherin is  the most elitist 
house and 
that Hufflepuff is the least exclusive. I would  assume that Gryffindor would 
be the seccond most exclusive followed by  Ravenclaw only becuase Gryffindor 
and Slytherin seem to have a lot of  alumni.

One more question, in the 5th book Hufflepuff was described as  "I'll take 
the lot and treat them just the same", does this mean that all  the 
Hufflepuffs 
are the other houses rejects? because if that were the  case I would think 
Crabbe and Goyle would be in Hufflepuff because they're  not Brave, Smart, or 
 
Ambitious.
