1.      DisplayName:  I want to add a space after the comma for example: Doe,john  This should be Doe, John
2.      Telephone:  I want it formatted as “(323) 442-2455”, not as “+1 323 442 2455”

I need help with the regex for the above 2 and then the Replacement string for Regex.Replace method.  Thank you.

1.
Find pattern:
,(?!\s)
and replace with
,
The comma on the previous line has a space after it. Note that the negative lookahead (?!\s) prevents a space being added if the comma already has a space after it.

2.
Find pattern "^\+\d\s?(\d{3})\s?(\d{3})\s?(\d{4})"
And replace with:
($1) $2-$3

I think this is the C# syntax:
  myResult = Regex.Replace(myString,@",(?!\s)",", ");
  myResult = Regex.Replace(myString,@"^\+\d\s?(\d{3})\s?(\d{3})\s?(\d{4})","($1) $2-$3");

So, using http://msdn.microsoft.com/en-us/library/e7f5w83z.aspx 
I'm not sure what to put for the replacement string for the Regex.Replace method though.  I mean what to put there so it would keep all the name's text and also adding that needed space after the comman?  Thanks.

Terry, where can I find information on what is this $1, $2, $3.....  Is this grouping in regex?

Yes, it refers back to the 1st, 2nd and 3rd groups defined by the round brackets in the pattern.

Ok, I can see that for the phone number.  However, I'm still not able to see that for the display name where I want to add a space where there isn't one.  The replacement string only has ", ".  That doesn't seem right, does it?

Yes - you're replacing a [comma without a space after it] with [a comma with a space after it]

What about the rest of the Displayname's text?  Are you saying it only replaces the comman? so if i have this :
Mystring = "Doe,John";
Regext.Relace(Mystring, ",@",(?!\s)",", ");
now Mystring would contian "Doe, John"?

Except there's an error in your code. It should be:
Regext.Relace(Mystring, @",(?!\s)",", ");
