Contacts sync to outlook?

[Papispico]

Comming from a ppc 6800...i was running into problems every time i would sync my phone to my laptop it would literally reinstall everysingle one of my contacts. so if i had for example a contact titled MOM. everytime i would sync my phone to my laptop i would end up getting 2 contacts titled mom.
SO what i did was i deleted all my contacts from my outlook program and sync'd my phone. It ended up deleting all my numbers on my phone. So i started all over again input alllll my numbers. SO now im here again now with the diamond pro. I sync'd once. Got all my contacts in. But im hesitant to sync again. Can someone help me with this problem. I want to be able Edit contacts in Outlook and sync it properly to my phone. How can i dictate which item..(outlook or phone) to be the primary item? TIA
