Handling Errors When Inserting/Updating a <List> of Objects/Records

Scenario:
In this example (not a batch process) I have a list of 100 contact records:  List <Contact> contactsToUpdate = new List <Contact> ();
// contactsToUpdate.size() = 100

I loop through these using a for loop,  I update a few records. Then I upsert them using DML.  Result:  a few records have been updated and a few are new & are inserted.  
if (contactsToUpdate.size() > 0) 
        {
            try 
            {
                upsert contactsToUpdate;
            } 
            catch(DmlException e) 
            {
                system.debug('The following exception has occurred: ' + e.getMessage());
            } 
        }

Here are my questions:

1)  If only 1 of those 100 records cannot be inserted do to something like a validation rule failing, will the entire insert fail or just the one record?
2)  Is there a way in the Catch that I could email myself only the records that fail and the reason - can I use the database.upsert in a try catch?
 

Thank you!

Hi BroncoBoy,
1. By using the above code if one record will fail all the records will fail.To acheive this you have to use:
UpsertResult Database.Upsert(sObject recordToUpsert, Schema.SObjectField External_ID_Field, Boolean opt_allOrNone)
http://www.salesforce.com/us/developer/docs/dbcom_apex250/Content/apex_dml_upsert.htm

In catch block you have to code to receive the records which are failing .You can access records using upserResult.
