Same here, 1d3 or 1d4 for paralysis is ok with me.
Shall we give them any of a Monstrous Spider's racial skill bonuses?
Brain spiders generally attack from ambush, dropping onto their victims from a ceiling or other high ground, or suddenly appearing from their psionic shadow form, imposing a -2 penalty upon opponents’ surprise rolls. They prefer to attack in groups, focusing their attacks on one or two victims and then leaving abruptly, hoping their poisonous bites do their work. They have been known to trail a party, waiting for one of the dead to be abandoned so they may feed.

Feats: 3
Multiattack? Improved Inititative? Track? (If so, ranks in Survival)?
Why the Bluff?
Although brain spiders are crude and even stupid, they have remarkable cunning when hunting. One of their favorite tricks is to use their body equilibrium discipline to stand over quicksand, a pit trap, or wreak ledges, goading victims into approaching them, and then attacking the trapped prey.
The evidence for tracking seems a bit thin, but Multiattach and Improved Initiative are fine.
The Brain spider's poisoned bite original had a -4 penalty to saves vs. poison, so maybe Ability Focus (poison)?
Oops. I quoted the same original text twice in my previous post. This was intended to explain the Bluff...
I'm fine with that, as the similar phase spider has that very feat.
