I'm having a problem with the Dark Brotherhood quest. I have to kill J'Grasska or something and he lives in Bruma. The problem is that he's not in the house when I go to find him. Is there another quest I have to finish before I can do this one?

I was kicked out of the Mages Guild, and I need to find 20 Dragon Tongue's and 20 Redwort flowers. Where can I buy/find them?

If i remeber this is the guty whos a master in hand to hand right so go to his house down the stairs and somewhere downstairs around a cprner theres piecies of cloth move them to find a trap door

...I know where that cloth is. THANKS! <3 <3 <3 If you can help with the 20 redwort flower, and 20 dragon's tongue..that would be helpful too!
EDIT: I killed that khajit quite easily! Thanks.

Oh man...I remember having to spend forever trying to find that trap door...He really was quite a simple kill, though. Oh well, I love the DB.
