What 3d modelling program do you use? This will help answer your questions. (Ooops sorry I see you use XSI - maybe somebody with experience with XSI can help, but I suggest you try exporting to a fairly standard format like .X or possibly .3DS for levels).
Also Giles is an excellent program for lightmapping a .b3d (or .ase, .3ds, .x, etc.) file. You just load in your model and place lights, render and save to .b3d format.
The lightmaps that you can make in Giles are superior (more optimised, easier to adjust) and more suitable for blitz3d than most commercial products.
So XSI -> Giles -> Bmax/MiniB3D (LoadAnimMesh command)
