Life Viewed Through an Amber Focus

In the Doctor Who books there is one where Rose's friend Keisha's brother goes missing or something.  Does anyone remember the name of Keisha's brother?  Most of my novels are packed away so I can't even tell you which one it is to check in.

Does anyone know what color Owen Harper from Torchwood's eyes are?  I've looked up Burn Gorman, but I've gotten both blue and brown from various sites.  Anyone know for sure? 

What's the most common mobile phone brand in England?  Not the service provider, but the phone maker.  I'm thinking along the lines of Nokia or something like that.  Or does anyone know what actual brand mobile phone Rose used in seasons one and two of Doctor Who?

What is Sarah Jane Smith's address?  I know it's Bannerman Road but what's the street number?  Thanks!

What was that thing called in Army of Ghosts/Doomsday that contained all the Daleks and they couldn't get out until it was triggered by a time traveler touching it?  I can't find my season 2 disc set.  Not the round gold ball but the other thing.  I'm thinking it had some sort of Biblical connotation.  Thanks.

What is Wilf's last name?  I'm pretty sure it isn't Noble, that he is Donna's mother's father.  Right?  Anyone know?

Is Donna's phraseology, "Stood there like a lemon," or "Stood there like a lemming?"

Can anyone tell me if Rose's friend Shareen ever makes an appearance in any of the Tenth Doctor/Rose books?  I'd like to get more of a sense of her for an upcoming chapter of YW?  I know she wasn't in any of the Nine/Rose ones.  Is she in the one with Keisha's brother disappearing?
