I upgraded to Snow Leopard, made a change to Address Book that I need to correct, tried to use Time Machine to find the prior version and it keeps pulling up the later ones info. How do I use Time Machine to restore Address Book from a few hours ago?

Question

This morning, I upgraded to Snow Leopard from v10.5.8. Then, I exported 11 contacts from our old Now Contact database, intending to import that info into Address Book. It was an experiment, as we have 1199 contacts in 20+ categories and want to eventually get them into Bento from Address Book. The export automatically created a file called Export.vcf on the desktop, after I highlighted the 11 contacts. I tried to look at the info, but when clicked it opens Address Book, which then simply asked if I wanted to import the 11 contacts to it. I clicked yes. Then in checking Address Book 7, not 11 contacts appeared. I clicked on "All Contacts" and there were 1630. We only have 1199, so where did the extra 400+ come from? Since I had already clicked twice on the Address Book window, I couldn't undo the import. So I thought 'Ok, I'll trash Address Book and go to Time Machine, find Address Book, go to right after the upgrade to SL, hit Restore and bingo. Nope. I keep getting the post-import info, not pre. Con someone direct me to a solution? I want to get rid of the import contacts plus the extra 300 or so ( I already had a hundred or so in several categories)? Then, I need to figure out (1) why ALL the old records were exported from Now Contact, (2) where they were hiding in that .vcf file when Address Book recognized that I only wanted to export 11, (3) why Address Book showed only 7 imports in the "Last Import" group, but showed ALL my contacts in the "All Contact" group, even though they should nearly all have been safely untouched in the Now Contact DBase file. PS, I am not especially computer savvy. Thanks for any enlightenment.

Booting From Snow Leopard Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.

5. Wait for installer to finish loading.
Drive Preparation and Installation
1. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is complete quit DU and return to the installer. Install Snow Leopard.
