Answers.com is a great site for info on these characters as well. I believe they even give info about the suits. I think its answers.com. I first learned of Prayer who is like Rau a clone of Mwu's father. However he suffers from a disease and dies during a fight with Canard that he was winning. His Dreadnought is rebuilt by Lowe using Canard's damaged Hyperion to make the Dreadnought H. Eventually in the end of X Astray Canard finds Kira at ORB who is with Athrun and Cagalli. He just passes him by thou as he has moved on and doesnt find the need to prove himself as not a failure. Then in the beginning of Destiny Astray he helps Lowe and crew make their flight using the Genesis Alpha facilitiy to goto Mars. What he does after that isn't known and I hope he makes another appearance in Destiny Astray of heaven forbit make an appearance in Destiny itself. Fighting alongside of Kira would be the shit.
