Consensual sex, extortion & rape case

I am a married man. last year I met 26 yr old girl on face book. we started chatting & I told her about my marital status. After some times I met her in a restaurant. second meeting was again in a public place. after three months of chats n calls of friendly nature, she expressed her desire to visit my city. she came by own, booked her own room for double occupancy n den called me. I went there, stayed wid her for two hours, had drinks & dinner & then came back. She left for her place. we met in similar way for three more times. every time she came by her own, booked & stayed in the d same hotel. around three months back, she suddenly blamed me that I didn't inform her about my marital status. Earlier she demanded that I either pay her money to the tune of 15 lakhs which was later reduced to 10 or divorce my wife & marry her. I was agree to give around 3 lakhs, the amount which she had supposedly spend on travels, dresses, hotels n number of other things. This demand was always done by her alleged lawyer friend & whenever I asked her about it, she always said that I should speak to her lawyer friend for this because she has authorised him to settle the case. I have call records of both such conversations. when I refused to pay such a heavy amount, they lodged an FIR against me, which was later transferred to my city. After lodging of FIR, I moved to HC for stay against arrest, which I got however quashing of FIR is still pending. The girl & her lawyer kept bargaining till last moment & she went to give her statement under 161 & 164 only after I refused for both of their demands. I also gave a complaint to SSP six days after her statement under 164 with all call records & chat logs. SSP forwarded it to concerned chowki for prelim enquiry. after one month of enquiry & scrutiny, my evidences were found correct & the investigating officer submitted his report along with charges as recommended by Jt Dir Prosecution. however police is not giving any decision whether they will register the FIR or not. Meanwhile, the Investigating officer of alleged rape case is about to submit charge sheet. Please guide on following - 1. Can I ask SSP office for copy of prelim Inquiry through RTI. 2. Should I go to court to register FIR. 3. What will happen after filing of chargesheet in the court. 4. Can bail be granted in one day or I have to go to jail. 5. Will lower court proceed with charge sheet or wait for outcome if I approach HC for quashing of Charge sheet. 6. Will cross case assist me or go against me as told by police.
