Usage Types required for NW04s

Hi.

I was initially planning to install the foll four usage types: AS-Java, BI-Java, EP, BI (Upgrade from NW04) and AS-ABAP (Upgrade from NW04).Now if I am wondering if I can just go ahead with BI and AS-ABAP and think about the other two later. Will the report designer work with just these usage types?Will that be fine or is there any other dependancy?

Cheers
