Hello dileep, and welcome to the forum. You can best choose the airport that's closest to the mountains you want to visit. If you want to get to the Jungfraujoch and Titlis, Zurich would make sense. The Swiss timetable
indicates how to travel in Switzerland. Trips to the Jungfraujoch and Titlis can be found here as well. And yes, January is a great month for a visit to such viewing points, as there will probably be lots of snow. Just mind that you should only get up if weather is fine.
Do you want to visit Paris by rail? If so, you could travel from Zurich, Lucerne or Interlaken to Montreux and Geneva using the beautiful Golden Pass route. From Geneva, you can catch a direct train to Paris. These trains can be found through the timetable
Since you'll only be visiting Paris, I think you shouldn't buy a rail pass for France, but just use regular tickets. Right now it's hard to say which pass is best for your 3 day stay in Switzerland, as you haven't finalized your travel plans yet. Our FAQ
can serve as a starting point in finding out which options are available. Once you know what your travel plans look like, it will be easier to pick the right pass.
