This forum is about Indigo Renderer and using it within XSI aka Softimage.
Indigo is a unbiased renderengine, there are no things like GI or Final Gather.

However, to answer your question:
If you want to render a animation with FG&GI you'll get veeeery long rendertimes, better to fake the GI-look as good as possible using bouncelights for example etc.
The most realistic lamps would be Area lights, but then again your rendertime will go way up.
I think Point or Spotlights with Shadowmaps would deliver the best looking results compared to their rendertime.
