Ruling on the Hajj of some person who entered the state of Ihram from Madinah and busied himself with transporting pilgrims

Q 1: I reside in Madinah and entered Ihram (the ritual state for Hajj and Umrah) from Abyar `Aly for Ifrad Hajj (performing Hajj only) and then proceeded to Makkah along with other pilgrims travelling with me from Madinah on the evening of the seventh day of Dhul-Hijjah. I then continued to transport pilgrims from Makkah to Mina and the way back throughout the day and the evening of the eighth day. Therefore, I did not perform Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah). I spent the night at Mina and stayed there until the morning of the ninth on which I went to `Arafah and then returned to Mina. Afterwards I went to `Arafah three more times and before noon I stopped my car near the Masjid (mosque) (Part No. 10; Page No. 171) of `Arafah in `Uranah Valley and stayed there. After Salah (Prayer), I went to the highest part of the Masjid, that is, in `Arafah until the sun set and then went to the car in `Uranah Valley and carried passengers with me to Al-Mash`ar-ul-Haram (Sacred Monument at Muzdalifah). I then performed Maghrib (sunset) and Isha' (Night) Prayers at Muzdalifah. I went to Makkah to refuel and arrived there before the Adhan (call to Prayer) of ?Sha'. When I heard the Adhan, I entered a Masjid in Al-Azizia and performed the congregational Salah before going to the petrol station.I went from Makkah to `Arafah transported pilgrims to Muzdalifah and arrived at 10:40 P.M., that is, before midnight. I spent the night at Muzdalifah until the Fajr (Dawn) Prayer. After well into the day, I went to Mina. When we arrived at Mina it became possible for us to park at a place next to the Jamarat (stone pillars marking the pebble-throwing area, Jamarat-ul-Aqabah being the closest to Makkah). At Al-Jamrah Al-Kubrah (largest pebble-throwing area, Jamarat-ul-Aqabah), I threw only seven pebbles and then went to Al-Haram (the Sacred Mosque in Makkah) and dropped the pilgrims off next to it. And took others to Mina. I continued travelling from Makkah to Mina and the way around until the 12th of Dhul-Hijjah. I then threw the three Jamarat, intending to be Muta`jil (pilgrim who hastens to leave Mina on the 12th of Dhul-Hijjah), at 12:55 P.M.I went to Makkah and performed Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Sa`y (going between Safa and Marwah) intending to travel to Al-Madinah or to Jeddah according to the circumstances. When I arrived where I parked my car at Al-Ghaza next to the Haram (Part No. 10; Page No. 172)  I found some passengers who asked me to take them to Al-Azizia and so I did. Once there, and still with my intention to be a Muta`jil, I found other passengers heading for Mina and so I took them there. I repeated this many times but I started to doubt my actions and asked one of the brothers there about my being a Muta`jil and about my Tawaf and whether it sufficed for Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah). He said that my being Muta`jil was valid but I must perform Tawaf-ul-Wada` some time before leaving. I spent the night in Makkah until the morning of the 13th of Dhul-Hijjah and then went to Al-Haram where I performed Jumu`ah (Friday) Prayer after which I immediately performed Tawaf-ul-Wada`.I then immediately traveled to Al-Madinah and took with me, from Al-Haram, some passengers. We arrived in Al-Madinah Al-Munawwarah after sunset. I performed Maghrib Prayer alone and ?Sha' Prayer in congregation, praise be to Allah, the Lord of the Worlds, at Al-Masjid Al-Nabawy (the Prophet’s Mosque in Madinah). Did I do anything wrong during my Hajj?
