Answer 1

Hello Srini,
Here 2 solutions:
a. One of the way is to create synonym of the objects of schema A in the schema B and grant the select on this objects.
b. The other one is, if you are the version 9.0.x of Oracle Reports is to use the JDBC data source. Using this data source you can create reports based on multiple connection.
But if you are in the same instance I would prefer the solution a (synonym / grants)
