Chidambaram and pichavaram are great places...
Madurai is beautiful...
Kerala is another budget destination if u use local transportation and lodges...
Route is pretty good till kalpa, Reckong peo... Swift dzire will have no problem. just check on the latest weather conditions on snowfall. driving in heavy snow would be risky around Kalpa. take care and safe journey

This is a very subjective thing.
Most people like to travel towards hills to enjoy cool breeze, many prefer beaches to feel the sun.
You have to decide your preference.
Set your budget, look for accommodation and suitable transportation, get some information about the place and how many days it will take to explore it.
3-4 days should be good enough 1 day - You will take one day approx. at jaisalmer fort as it is a very big fort to enjoy fully
1 day - You will need to travel within the city to see its famous landmarks at ease
1 day - to go to Longewala post tour
1 day - Sand dune bashing if you interested you could add one more day just to sit and relax and enjoy
