yes install it. the update fixes bugs and security flaws and youre much better with it installed than without it. i have never had a problem installing Apple's updates thru Software Update.

however some of the problems users where experiencing was due to a connection drop when downloading the update and Software Update was installing an incomplete package. just make sure you dont disrupt the download and keep your bandwidth free or download the update from Apple's website instead.
