Fragmotion is an excellent tool for .b3d models - if you wish to edit the animation you may find PaceMaker useful as well. For animation its a bit more intuitive than Fragmotion and also allows you to share animation between models, save individual sequences or skeletons and create idle or death scenes with a couple of mouse clicks.
I will be releasing the current version of PaceMaker for free shortly so it won't cost anything to try !
