Multiple rogues in a drow party is probably a good thing, really. Twice as many chances to spot traps or ambushes, twice as many back stabs or other miscellaneous forms of sneak attacks, can't really think of a negative. Plus once we get up in levels a bit, it will make for some fun once my Wizard learns to cast invisibility.
Also, while reading through Drow of the Underdark, I've found an interesting suggestion in the book regarding female drow characters. Since Lolth resides in the abyss and is served by demons, drow Warlocks are considered favored by her, and a female drow warlock can attain similar ranking as a cleric, as long as they meet the same standards as the other priestesses, mostly because Warlocks can gain their power from demonic interactions. Just some food for thought for anyway wanting to play a female drow but not wanting to be a cleric.
That's partially incorrect. Warlocks are indirect servants of Lolth, they serve her demon minions more than the Spider Queen directly. And should a female of any status (or should she end up proving herself) whatsoever be a Warlock, she would become a priestess. The recognition, power, and honor tied to being a priestess is something no female would pass up, with the way Menzoberranzan's society is ran. The priestesses have all the power.
Any noble born (daughter(s) of a Matron mother) are going to be priestesses (at least primarily; multi-classing they can be anything else, but their cleric level is always going to be at least 1-2 levels higher than all other classes, for example cleric 5/fighter 4 or cleric 4/fighter 2/warlock 3. Both 9th level characters.)
Female commoners, are usually just your house chapel tenders and ones who fill the prayer circles during large ceremonies. And never really achieve "great" power. Those that do or want a chance to, have to show some sort of talent and Lolth most give her blessing. Society again places theses individuals as priestesses, because again that's where the power is.
Even the lowliest priestess commands some respect within the society, while those within her own ranks can "push" her around...none of the males can. Only someone with a position and house behind them, such as the Archmage of Menzoberranzan, can really get away with sort of ignoring lower ranking priestesses. And even then, he even has to watch his steps about how and where he does such things. Or some of the other male Masters of the Academy could possibly get away with such things as well, but again it's the where, how, and also how far they push the limits. If they cross a certain line, Lolth herself might just send one her handmaidens to intervene and slap the male back in line.
For female characters looking for options my suggestion is to pick one other class, and keep it one level behind your cleric level. While the 3.5 multi-classing rules mess things up a bit, the class it really messes things up for is fighters (or any other combat oriented class, looking to max out his/her attacks per round and base attack bonus, which you have to do by 20th level). For everything else, such as spells per day... you can take till 10 millionth level to max out, because it is based on your class level. Only your base attack bonus (and number of attacks per round) and original base saving throws are set in stone by 20th level; thereafter you only get bonuses per the rules in the Epic Level Handbook. But all other class abilities, such as spells per day and what not are still determined by your class level, so multi-classing does not hurt spell-casting classes.
What is the tech level in the city?
Not quite sure what exact sort of answer you're looking for. I mean, if you're wanting to play with guns, flamethrowers, or that sort of thing...this isn't Warhammer 40K type stuff.
