City of the Spider Queen questions

[Tahlathali]

Ok, so to those that haven't seen my recent questions, it is me and my 2 cousins with 3 10th lvl gestalt characters doing this campaign adventure. While prepping for the next session, I realized (a little late I know but I've had the book for a long time and never tried the adventure) that it is 3.0 and not 3.5. It really hit me when I saw the hidden fang of lolth girl in room S3. I have also noticed that a lot of the spells used by mages are assuming 3.0 durations and not 3.5 (i.e. bulls strength and the like). For the fang of lolth, should I leave her as is or do I need to update her? I haven't seen a fang of lolth class yet in 3.5. Since we are playing 3.5, is there much I need to worry about updating?? or is it still pretty stable just leaving it as is?

Usually, I've seen that unless there are some really severe power differences, it doesn't matter.
Having a monster with Bull's Strength, or whathaveyou, that lasts for 1 minute or 1 hour doesn't usually matter. Why? Because the fight will probably be over in less than a minute anyways. One enemy, if level appropriate, probably won't last long against an entire party.
