Help! How do I delete a pending OS X software update???

Question

I forgot to turn off "automatically check for updates" in the system preference, so I found my computer had already downloaded the "updates" from iWork '09 to the latest versions of Pages, etc.
Of course, this is a disaster -- the latest Pages, Keynote etc. are broken since functionality has been removed so they are more compatible with the toys, uh, I mean iPads.
Since these updates on my computer have been downloaded but NOT INSTALLED yet, how can I DELETE those downloaded but-not-yet-installed update files and save my programs from being mangled by the latest update? Do I just keep hitting "remind me tomorrow" for the next few years?
I searched all over and cannot find the answer.
I hope you can help me. Otherwise I think I have to completely reinstall Yosemite to get back to functionality.  (And no, there's no backup since I just installed Yosemite a few hours ago.)
Thanks!

These "updates" will put another version of Pages, Numbers and Keynote on your computer beside the iWork'09 version. Once is done, in your /Applications folder you will see Pages, Numbers, and Keynote and also a folder called iWork'09 where you will have an access to older versions of these apps.
In other words, these "updates" won't replace your iWork'09 - you will have an access to both versions at the same time and you still will be able to use old version of iWork'09.
Always remeber to have a Time Machine Backup (or other sort of backup) of your data. You can save yourself a bit of stress...
