Hi Sharmadeepa and welcome to MySwissAlps!
For ideas of what to do in Zurich click here and Luzern click here. I would spend more time in Luzern over Zurich - much more to do, especially outdoor activities. Perhaps just book your last night in Zurich and the other 3 nights in Luzern?
The Swiss Travel Pass for 4 days is your best option I think. If on the last day your only trip is from Luzern to Zurich (or Zurich to Zurich airport) then the point to point ticket would be relatively cheap.
Weather is hard to know in advance of course but I would expect the mountain tops to be quite cold - 0 or 5 degrees Celsius if you are lucky in late October. In the towns it would be maybe a max of 10 degrees. Have a look at the weather forecast for the towns before you travel to get an idea for packing - the mountain forecasts aren't reliable until 24 hours before.
