Edublog hompage problem? Please do help

Well I don't know really how to start with. With almost all the plugins and themes when I start liking it...and reach halfway through - I start facing problems.

Well I am attaching the image, marked with arrows. This is homepage - where service boxes are enabled on my site...but how to remove this (marked in the image) called "Latest news" and related stuff below this. See when I try to use right sidebar...i comes far below all this...I am not interested in this.

Kindly help to remove this latest news and few blog posts that appear below this.
