Help new contact - phonebook app?

[ProRezOnline]

I am new to the captivate. I have all my contacts in my phone now, about 300. Is there a way to either group or create groups of them and then set one of those groups up as the contact default? I know some phonebook apps probaly do this but are limited in thier information. I am looking for the full contact info (with phone numbers) and then isolate those I use frequently into such a group...

Suggestions?

You can easily create groups, just click on contacts and then groups at the top and then add to a group or create a new one. I don't kow if it possible to assign a group as the default however.
