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.

Thanks
