If you're not rooted, you should be able to just take the update. IMO, most of the issues are coming from rooted devices that may not have been totally clean (stock rom, stock recovery, total factory reset) when the update was taken. That's not a worry for a stock phone.
If you want to root afterwards, the CF Auto Root is the way to go for sure.
