Planning to take Divorce from Wife

I am having a problem in my life with my Wife. She is currently staying with me in my Father home. We have 1.6 years of daughter from our marriage. She is threating me for Interim maintenance which i understand court will decide after hearing arguments from both side. My question is related to her rights in the property currently owned by my father (Given to him through will by his father). This is the same property where we stayed after our marriage for a 3 years before . 1.) Would this be self acquired property or ancestral property? 2.) What are her rights in this property? 3.) I don't want to stay with her anymore. Can i go ahead & file divorce? Would there be any implications? 4.) I am planning to move on Rented home with her , Will this decision help me in my case ? 5.) How much % she have right for maintenance amount from my salary ? Is it 33% ? 6.) I am having handsome salary with Shares of Company ? Is she have also rights on my Share or only she can claim on my Salary ? 7.) She is un-educated only 8th pass { Is this help me in any way )? 8.) What steps should i follow which help me to make strong point in my case .
