Answer 1

This is not how partitioning should be used (never mind incorrect code and not for example also using dynamic SQL in the forall statement).
Oracle's CBO has the intelligence to perform partitioning pruning - to decide (correctly so) which partitions to use and not use for a specific SQL statement.
There's absolutely no reason to specify the partition name in an application SQL statement. In most cases, it will also be the wrong to thing to do.
Partitioning is a physical feature of the database table. It is not part of the logical database implementation. Application SQL must deal with the logical database layer - not physical. And it should be obvious why...
