Can I uninstall and reinstall "Pages" without losing files?

Question

My Pages program may be, ...IS, ...corrupted.  (Maybe by a disgruntled co-worker?)  When I type a client's name, Pages automatically misspells it.  Same with my own name, and perhaps with other words I've not yet discovered.
I suppose I should uninstall and reinstall to see if the malware is limited to Pages or if it's a system-wide problem.  But I don't know how to do that.  I've never uninstalled a program and do not know what might happen to various files, if anything. 
I've tried fixing the problem in the automatic "spell check" function.
Ideas? Advice?

Possibly, however, before you remove it try removing the preference files from the application These can be found in Users/yourname/Library/Preferences or /Library/Preferences.  Since the autocorrect uses the dictionary found in Users/yourname/Library/Spelling, you may want to see if the dictionary was corrupted as well.  If it is system-wide you should see it in other locations such as Numbers or if you are using Lion you will see it in Safari as well.
If you don't see the preference files also check both /Library/Application Support, and Users/yourname/Library/Application Support.
