Help needed finding spare parts for Transformers Prime Deluxe Toys

Hello. I'm new to Seibertron. We had friends stay over for about a month. Their children were specifically instructed NOT to play with my small collection of Transformers Prime toys. When they left, I inspected my toys and discovered some parts missing or damaged (I wish I new how to upload pictures because it would make it easier). I'm hoping someone can help me with the following:
One of Arcee's blades (I believe the right side if you were riding the bike);
Both of Wheeljack's katana;
One of Starscream's missile clusters;
One of Predaking's double rockets (not the huge Predaking);
A spare left forearm for Bumblebee (Not Bumblebee, but he does NOT have the Autobot sign on the end of his bonnet/hood).
Any help or leads would be greatly appreciated or is there a spare parts forum or network somewhere? Thanks!
