So this is assuming that you are going single-class Fighter, Blackguard as soon as possible, and then more levels in Fighter.
Well you need Power Attack, Cleave, and Improved Sunder to even *be* a Blackguard. If you are tricky, you need the feats that allow for tricky maneuvers, so Combat Expertise leads to Improved Disarm and Improved Trip. Improved Bull Rush also has its uses, as
has shown.
So for feats you get:
1 Power Attack
F1 Cleave
F2 Improved Bull Rush
3 Sunder
F4 Combat Expertise
6 Improved Disarm
F6 Improved Trip
before you hit Blackguard. Obviously you need to max out ranks in the cross-class skill Hide for 7 levels, and well as spend at least 4 skill points buying 2 ranks of knowledge (religion). It is too bad Bluff is not a class skill for either fighter or blackguard, but Intimidate is a class skill for both, and it has a few tricky combat uses.
For stats, the trick is figuring out a dump stat for the 6. Usually strength and con are needed for fighters, but you want an int of at least 13 for some tricky feats. Wis and Cha are good for blackguards. This leaves dex at the dump stat.
So, put the 10 in Int (goes up to 12 with race, then +1 to it at 4th level). 13 is pretty smart (draconic is a pretty good language, but your background might commit you to the Drow silent hand gesture language). Put the 17 into strength (you always need strength), the 14s into chr and con (chr goes up to 16 which is great for spells and smites; Con goes down - sorry about that). The 13 can go into wisdom (becomes 15, so you keep your wits and spells about you). Dex goes up to 8 with the racial bonus.
At 8th, 12th, 16th and 20th level I would keep pumping up strength, but that is just me.
Items? Well shadow armor would help with your hide score, and to add to the "hide in shadows and then sneak attack" you could get a sword of subtlety. Perhaps even an intelligent one, to get extra "tricks" from its independent actions. Or maybe add "unholy" and "axiomatic" or "bane" depending on what you predominately fight against (very interesting that you went LE instead of CE for your Drow -- trouble with the family?) A spiked gauntlet is nice both for the "evil" theme and to make sure that you are never unarmed.
A feat to take later in your career would be Leadership, as one great "trick" is "use your underlings to lead your enemy into an ambush". Other high level feats of note:
Craft Arms and Armour (your Blackguard levels make you a spellcaster, after all) to allow you to tweak your armour and weapon(s). Once you have a weapon you want for the rest of your career, you can risk Weapon Focus, Weapon Specialization and Greater Weapon Focus, but there are other options. Quick Draw, Point Blank Shot and Precise Shot are a nice combo for using ranged thrown weapons (do not overlook the humble Javelin . . . of Lightning) when you have to. And while the three "saving throw" feats seem boring, they can save your hide (Great Fortitude, Iron Will, Lightning Reflexes).
Sorry about the +2 LA, but you did say you wanted Drow.
More esoteric things to look for (since you are not afraid of LA). Try to get bitten by a lycanthrope or vampire - suddenly you get a wealth of options. This assumes your DM allows you to remain a PC, mind you, and you might not like to change your alignment (but that still leaves wererat as a lycanthrope option).
Hope this helps.
