Can a muslim pray for his non-mulsim mother who has passed away?

I have a few questions concerning parents:
1. What right does my Mother have over me? 
2. What right do I have over my mother? 
3. What do I have the freedom to do (which is Halal or Mubah, Ofcourse) without my Mother having the right to stop me? 
4. When does the Father have the final say in a matter? 

I love my mother very very very much. She is very over protective, and sometimes I feel like I'm in chains. I know she is doing it out of extreme love for me. How can I tell her that I need a little choice of my own in life.

For how long does Allah forgive a person's sin? If he repents and seeks forgiveness from his sin, then goes and commits the same sin again, then he seeks forgiveness again then commits the same sin again, and so on, does Allah forgive him or does that mean that he is not sincere towards Allah, especially if he repeats that sin after a short while, but he does not stop seeking forgiveness?

How do we as Muslims living in the west maintain an Islamic Education for our children. Primary and secondary education up to the age of 15/16 may be provided in Muslim schools (which are also very expensive), but as for Higher Education there is no such Islamic Institute. 

Even on the secondary school level on the agenda of Curriculum, we do not have books that deal with the branches of knowledge that are available in secular institutes, such as; Political science, Sociology, Psychology, Pedagogy. Please advise on how we should go about bringing about an Islamic Education system for our Youth in the west (bearing in mind that it is near impossible for us to migrate to Arab/Muslim countries because of the restrictions on immigration etc.).

I want to make my children keen to pray, because they will pray once then forget about prayer many times. I always advise them and pray to Allah to guide them. How can I encourage them and make them love prayer?.

Is it true that the person who is used to studying in Islamic schools, and has no previous experience of studying in non-Islamic schools, will never be able to connect with the environment that surrounds him, where most of the people are non-Muslims and that he will grow up shy and will never find any way to succeed either in his academic life or in the workplace? What is your opinion about that?

What is the Islamic ruling on the issue of imitating the kuffaar in their customs and dealings? What are the guidelines concerning that in Islamic sharee'ah? Is every imitation of the actions of the kuffaar regarded as a haraam kind of imitation, knowing that there are many things that the kaafirs do that are not haraam and are not condemned by sharee'ah, where the one who does them does not do them merely to imitate the kuffaar, but because he thinks those things are good, as Ibn Mas'ood (may Allah be pleased with him) said: "What the Muslims think is good is good before Allah"?  
Please advise us, may Allah honour you, and please give me a detailed answer and explain to me the guidelines on this matter.
