Passing the Miqat without assuming Ihram

Q 1: On Monday 27/11/1411 A.H., I went to Jeddah to meet my parents who were coming from Egypt to perform Hajj. I also intended to perform Hajj on behalf of my deceased father-in-law as I have performed obligatory Hajj for myself. Furthermore, I intended to perform Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between) because of my long stay at Makkah. I took a bus to Jeddah intending to enter the state of Ihram (ritual state for Hajj or `Umrah) from the Miqat (site for entering the ritual state for Hajj or `Umrah) called Yalamlam, the Miqat for Yemenites and those coming from the south. I was overcome by sleep and the driver did not stop at the Miqat and I woke up after we had went beyond it. So, I entered Jeddah without Ihram. I met my parents and accompanied them to Makkah and I stayed for about one week without entering the state of Ihram or performing any of the Hajj rituals. I asked a shaykh in Al-Haram (the Sacred Mosque in Makkah) and he said that if I did not enter Ihram until the time of my question, I would have to go back to the Miqat to enter Ihram and no Fidyah (ransom) was due (Part No. 10; Page No. 110) upon me. However, if I had already entered Ihram, I would have to pay Fidyah for not entering Ihram from the appointed Miqat.Moreover, I asked another shaykh who told me that the religion is easy and not difficult and that I have to leave the outskirts of Makkah and spend the night there, then enter Ihram from any given Miqat, such as Al-Tan`im. I have read in books that Al-Tan`im is only for `Umrah. Some people told me that I have to do as the people of Makkah do because I stayed in Makkah for more than a week. So I can enter Ihram from my house in Makkah. Accordingly, I entered Ihram on the seventh day of Dhul-Hijjah to perform Ifrad Hajj (performing Hajj only). Hence, I completed all the rituals required. Do I have to pay Kaffarah (expiation)? Please guide me as some shaykhs said that I must offer Fidyah. May Allah benefit you.
