If I have to buy a SNCF Transilien, TER or TGV Inoui train to/out of Paris, is the Metro portion to/from Gare Est/Lyon/Nord covered by the SNCF ticket or do I need to buy a t+ ticket?Similarly, does my RER ticket from/to CDG cover the Metro portion to/from Gare Nord?\'Thank you.

No a SNCF intercity train ticket (TGV Inoui/Ouigo) does not include/cover Paris RER/Paris Metro trains upon arrival / before departure. A separate Paris transport Ticket t+ will be required for city transit connections in Paris.
Yes, RER tickets such as for the RER B from CDG Airport to Paris Gare du Nord, do include Paris Metro or other RER train transfers with the same RER ticket. The last transfer must occur within 90 minutes of the initial RER ticket validation (1st insertion into fare gate). The total validity time of an RER ticket is 2 hours (i.e. no more transfers can be made after 90 minutes; the ticket still permits you to be on trains / inside fare-paid areas until 120 minutes).
Same applies for RER tickets going from Paris to CDG: that RER B ticket for "Paris to CDG" is valid for all Metro train connections prior to boarding the RER B towards CDG. All RER train transfers within zone 1 prior to RER B to CDG are also included in the RER ticket to CDG. So you could start your journey on Paris Metro line 1, Chateau de Vincennes station, using the RER B ticket for Paris to CDG, transferring at Chatelet les Halles from Metro 1 to RER B and using the ticket to exit the RER system at CDG Terminal 1 or Terminal 2 train stations.
