SAP -> BO XI Newbie

I know a bit about both SAP and BO both and wanted to understand how these products would work.

1) If I have a) BI Query and b) Oracle Table/View can I combine them in the same BO XI universe and have user report against that universe using either Voyager or Webi?

2) If I have BO Crystal Reports do I need to have a universe created to be able to access data from a SAP BI Query?
