Answer
(Fatwa: 38/17/D=1433)
(1) Yes in this case, only sadqah was wajib on you i.e. 1.633 Kg wheat or its price. It was already paid by ten Riyals. Now you have to do nothing.
(2) After head shaving and tawaf ziyarah, wife is halal though yet the Rami of two days was pending. Hence you did not do any thing contradictory to hajj.
(3) After tawaf wida while going to Madina you were not in the state of Ihram hence the forbiddances of Ihram were not applicable to you and it was lawful for you to kiss your wife as well as have intercourse. Hence what you did was not a sin. Do not have any doubt. In-sha-Allah, your hajj shall be accepted.
(4) It is not haram, rather it is allowed in excessive lust.
(5) Be regular in all worships, offer salah with jamah, keep away yourself from sins in particular avoid watching obscene things on TV etc, earn halal livelihood and avoid haram earning. Be regular in reciting Durood and doing zikr as well as recitation of the holy Quran.
