Answer 1

Andrew is partially right.  With apps that are still running, they are running regardless of being suspended or not.  A restore should be her last option. as she will lose anything added since her last back up.  And there should be NO reduction in speed as the update was made compatible with all phones included in the update. 
I recommend the following.
1st, delete all apps on the phone that are not being used.  They take memory and speed since almost all apps run in the background checking for notifications.
2nd, go disable all notifications you don't need.  This will help with speed AND battery life.
3rd, location services....  Go adjust this... if you don't NEED it on, turn it off.  It will reduce usage on the phone, and again save ALOT of battery life.
4th, organize apps into folders.  this will ruduce "pages" on the phone, and increase speed.
5th, clear browsing history. 
6th, delete emails, texts, contacts that are not needed.  ESPECIALLY Spam folders!!  some of us never clear spam, and there could be a large amount.
7th,  Do a hard restart.  While the phone is powered on, hold the home button and power button down at the same time.  Keep holding while the phone suts down and keep them held down until the Apple logo reappears. 
If this does not help, then she needs to take a record of all contacts shes added since her last back-up, email all photos taken since her last back up, so she can save them back to the phone,(DO NOT rely on photostream, because once the restore is done, those photos will be taken from the stream.)  She will need to do the restore off her computer and the update through iTunes.
