Samsung Moment :: Groups Missing In Moment Gmail Contacts And Call Waiting Drops Call

In Gmail I have my contacts sorted by groups, easy enough, on occasion I need to add a new group or move a contact from one group to another, which is easy enough using a pc and my Gmail account. However, I cannot seem to add new groups or edit existing groups on my Moment. I can see the groups, I can sort by groups, but I cannot find an option that will allow me to add or edit any groups. Does anyone know how this is done on the Moment? I suppose I could use the browser to log on to my Gmail account and change it from there but isnt that sort of redundant since I am on my Gmail account using the Moment? Also, maybe someone knows when Moment contacts sync with my Gmail why dont the contact photos sync? One more thing, anyone ever on a call and it goes dead and after a few seconds the phone rings with unknown in the caller ID. When answer it is some from my address book that should have appeared in my caller ID Anyway, now I have to quickly hang up on this person to call the person my phone hung up on to receive this call. Its like the call waiting gets disengaged and hangs up the present call to allow the new incoming. I also had this problem on a HTC Hero I had before I got the Moment also.
