Combining Navigo Pass with an SNCF point to point ticket outside Île-de-France
We will be travelling on an SNCF Intercités service from Paris. We both have Paris Navigo passes, one weekly pass and one monthly pass, both of which will be valid on the day of travel. The service we will be taking departs from a central Paris station, which is in Navigo fare zone 1, to an SNCF station which is outside the Navigo fare zones (and therefore also outside the Île-de-France region), specifically Vernon-Giverny.
Is my understanding correct that as this journey is at the weekend and the journey is entirely within Île-de-France; the holder of the Monthly Navigo pass is entitled to travel the entirety of this journey without needing to purchase an additional ticket? [This question is incorrectly formulated and therefore does not require an answer anymore. Thanks to @jcaron for pointing this out.]
Secondly, is it permitted for the holder of the Weekly Navigo pass to purchase a point to point ticket to get them between the last station within the Navigo fare zones and the final destination station? Thus saving on purchasing a point to point ticket to cover the whole journey, a good proportion of which will be inside the Navigo fare zones.

EDIT : I missread your question, your assumption is not correct. See below
For the first question, your assumption is not correct : weekends are "unzoned periods" where your 2-zones Navigo Pass can be used for any zones within the Navigo zones. Other "unzoned periods" include bank holidays, school holidays for Ile-de-France and during the summer (mid July to mid August). Source. NOTE: this is only valable for the monthly pass, this doesn't apply to weekly pass.
EDIT : this doesn't allow you to use the pass for any destination outside the Navigo fare zones, the unzoning is only relevant for the 2-zones pass you can buy (by opposition to the all-zones pass)
For the second question, nothing prevents you from doing this and you will save money applying this scheme. Just make sure you have enough time to get the new ticket as some destinations are crowded and you might wait up to 10 mins before being able to purchase a ticket. This is called "Complément de parcours" Source
