Well I'm not sure how Categories would help me send emails to those
hundreds of people? Can you explain?


Yes - view Contacts by Category, highlight the Category and do
Actions-Create-Message to Contact or Tools-Mail Merge


Also, all the information is already entered for those hundreds of
contacts....would I have to re-enter all of that information from the
fields into categories?



No. All Categories does is to add a "sorting" index to each Contact.
And you can add a Category to all your 500 contacts at once - select all the
contacts, right-click and choose Categorize...
