Not needed as when run using the Catalyst Install Manager it uninstalls the old driver
before installing the new, that's why the screen goes black and flashes a couple of time when installing the new driver.

For the 64 bit version of your GPU card driver go to SAPPHIRE- HOME
For the 32 bit version go to SAPPHIRE- HOME
Again not needed (especially Driver Sweeper) unless you are troubleshooting or experiencing a problem when updating, and if DS is used improperly can cause more problems that it solves(think of those times you have seen someone use it and end up stuck with the good old "standard vga", and quite often the only way to fix it is a re-install of Windows if a backup wasn't made beforehand).
Also unless it is a laptop, ATI drivers
are ATI driver regardless of who the card was made by. At most the only difference from the one from Sapphire or any of the other AiB's is it may show the manufacture's name somewhere during the install and/or in CCC after (just had a look at the one from Sapphire and all they did was take the same download available from ATI and put it in a zip file).
To answer the original question, over the top by running the downloaded driver file as the Catalyst Install Manager takes care of uninstalling the old before installing the new.
