I forgot to answer this one: false, always, per ECMA-262 Edition 3, 
11.9.6, quote:

The comparison x === y, where x and y are values, produces true or 
false. Such a comparison is performed as follows:

1. If Type(x) is different from Type(y), return false.
2. If Type(x) is Undefined, return true.
3. If Type(x) is Null, return true.
4. If Type(x) is not Number, go to step 11.
5. If x is NaN, return false.
6. If y is NaN, return false.
7. If x is the same number value as y, return true.
8. If x is +0 and y is  0, return true.
9. If x is  0 and y is +0, return true.
10. Return false.
11. If Type(x) is String, then return true if x and y are exactly the 
same sequence of characters (same length and same characters in 
corresponding positions); otherwise, return false.
12. If Type(x) is Boolean, return true if x and y are both true or both 
false; otherwise, return false.
13. Return true if x and y refer to the same object or if they refer to 
objects joined to each other (section 13.1.2). Otherwise, return false.
