Side Bar PROBLEMS

i have recently upgraded my WP from 2.04 to 2.2. i have 2 problems…

1. The side bar is all the way down the bottom of my page under the content. But my sidebar works on anyother page apart form the home page!.

2. i get this database error :

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ” at line 1]
SELECT cat_id, cat_name FROM

My site is PureWire.net
