How to reduce blur in low light photos?

not with your current setup. You'd at least need an off the camera/hotshoe flash that can be pointed away from the subject and/or bounced off the ceiling or wall etc.etc. Your best bet would be to check out Scott Kelby's books at the amazon link below. I'm an amateur photographer as well, and he has helped immensely in getting my photography better. That said, nothing will help as much as experience, so keep plugging away at it, display your pics at flickr or Pbase, get people to critique it and you'll get better. Good Luck
