Basic export import...

Question

I am testing export from oracle 7i to 11g.
1) Is 'incremental' export supported only on FULL database exports? Can this option be used only on a specific schemas?
2) If i want to export full database and import, does it allow the option to remap users i.e. say in full export we have 3 schemas for user USER1, USER2, USER3 when importing can i remap these to NEWUSER1, NEWUSER2, NEWUSER3?
3) For exports, say 1 take a full DB export which includes TBLA with 1million rows. Next day I take incremental export and two rows are added/changed in TBLA will the incremental export, export all rows in TBLA or only 2 rows which were addeed/changed?
