Hi there Liz and welcome.
Are you getting any error messages when it fails, if you are then please let us know what they are as this may help someone resolve your problems? If it is just timing out it could be server pressure when you are trying to upgrade, Apple has just gone for one of the most incredible software releases I can ever remember.....2 OS upgrades, 1 completely new release (iCloud), many programme upgrades (iTunes, pages, keynote, etc) and to top it off a new hardware release (iPhone 4S) so its more surprising that millions have upgraded seamlessly so you may have to just give it time.......but any other information about your problems will help us to help you. Good luck and I hope we can get you sorted out.
There is lots of good advice and info on here plus plenty of members all too willing to help with any problems.
