I think Dragon #298 is a must for anyone planning to play a drow or for a DM that plans to use them in a game.  I've never read any D&D novels so perhaps they are very insightful, but the article in Dragon #298 really hammered home for me just how evil and sinister the drow are.  If you haven't read the article then it's a must; learn why there are so few drow twins born.  

  It all really hammers home what the race is all about.  They are damned in a very unique way: by the Sendarine, by Lolth, and by their cruel environment in the Underdark.  The psychology of the race can be absolutely fascinating to explore with a character no matter what his/her personal allegiances are.  
One thing I always remind my friends is that if there are half-drow and half-orcs in the world then that means the social dynamics are a bit more complex then "Mooks!  Let's get 'em!"  Depending on your personality, the DM, the gameworld, and the location, playing a drow or half-drow might be fun or grating.
From a min/max perspective you have to ask yourself whether you'd like to trade 2 levels for 120' darkvision and SR as a drow.  In the case of spellcasters that's a big debate.  Personally, I'd rather have the caster levels.  For fighters I wouldn't hesitate very long to trade the BAB and a feat or two for the darkvision and SR, especially when their saves are nothing to shout about.  120' darkvision + longbow = cheese
