Lucas has given you good guidance, although you could help us by being more specific about the interests that direct your trip.

A central location to consider, while studying those that he linked, could be Luzern. I'd suggest that no mater what, Luzern is a better base than Zürich, easily reached on arrival at Zürich, unless your interests run to culture(museums) and high-end shopping.
You will find good train service to Paris from either Zürich or Geneva to Paris, but perhaps it might be a bit better from Geneva. The timetable linked by Lucas is the place to start.
