Answer 1

Can you just try something like:
1)
update user_sdo_geom_metadata a set a.diminfo= your_new_diminfo_without_z_dim
where table_name ='...' and column_name = '...';
2) assuming Z dimension is the last one.
declare
newdim MDSYS.SDO_DIM_ARRAY;
begin
select diminfo into newdim
from user_sdo_geom_metadata
where table_name ='...' and column_name = '...';
newdim.trim;
update user_sdo_geom_metadata a set a.diminfo= newdim
where table_name ='...' and column_name = '...';
end;
