I know this is a moderately old thread, but these little things are exactly what I love about the trilogy.  I've got a few that I've collected over the years:

The number 6 is considered the first mathematically "perfect" number being the sum of its divisors.  (1+2+3=6)  Neo is, of course, the 6th integral anomoly.

Thomas Anderson's place of business is a software company called "Metacortex".  The word "meta" as a prefix means "to transcend" or "go beyond".  The word "cortex" is used to describe the outer layer of grey matter surrounding the brain.  So "Metacortex" literally means "transcending the boundaries of the mind".

Thomas Anderson's apartment number is 101, which in binary code translates to the number 5.  5 is the 6th number in binary if you count 0 as the first number.  (This is possibly another reference to Neo being the 6th anomoly.)

The restaurant where Neo, Morpheus and Trinity meet The Merovingian is called "Le Vrai Restaurant".  "Le vrai" in French means "The truth".  The Merovingian tells them that cause and effect, or causality, is the only real truth.  He also states that the reason the three of them came to see him is because they were told to do so.  So quite literally, cause and effect lead Neo, Morpheus and Trinity  to "le vrai" or "the truth".

I could go on for hours about this stuff.  I love it.  But alas, I must get back to work.  

I'm definetely up for this.  It's taken me a cumulative 8 days of gameplay to reach 23.  Needless to say, I'm eager to grind with some higher level players.
