What is the importance of being truthful, both in personal and business relationships, in Islam? Is lying ever considered and (acceptable) action?

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.

I want to serve my Religion, what should I do?

How can a muslim who is really lacking self confidence become a more confident person? He has tried so many things but has yet to overcome his nervousness when talking to people. May Allah reward you with good for your effort.

Perhaps my question has been asked many times before. It is about mortgages in non-Muslim countries. We live in a western society and we live in rented accommodation so as to avoid riba. Recently we found out that there are no houses for rent, and 96% of the market is based on mortgages. All houses are offered for sale only. Some of them told me that in this situation it is permissible for me to  buy a house by means of a mortgage and, moreover, it is possible to get the mortgage in the name of family insurance, so that the individual does not pay riba or a mortgage; rather it is paid by the insurance. Is it permissible to get a mortgage in the name of the family insurance, in such a way that you and other trustees or borrowers are not dealing directly with the bank and the lawyer takes care of dealing with the mortgage on your behalf?
I hope that you can advise me as to whether that is permissible or not.

I have very difficult question and I think this is my only hope that you can help me to find the answer.
I am a Russian Jewish girl and I know this Muslim guy for over a year. The longer we know each other, the more problems and difficulties we face. Not in the religious or cultural ways. We love each other and there is an issue of whether he can marry me or not.
He is a very good Muslim and he comes from traditional family. I am very fond of his beliefs and beliefs of his family. I was born in a very agnostic country and couldn't be properly introduced into any religion. It was forbidden. When I came to the US I started my research on different religions and found out that my beliefs do not really match all Jewish sayings. I did a lot of research on Islam and by looking at him and a couple other Muslim boys and girls, and by reading Quaran, I have a very strong feeling that I could become a good Muslim. I want to go to school to learn the culture and religion more precisely, to learn the language. I contacted the mosque and was ready to go... but I faced the issue: would I be accepted as a Muslim sister like other people who came from different religions except Jewish? Jews and Muslims are in big contradictions and I know that friendship is almost impossible. I am praying to God (in my home language - Russian), to lead me the right way to achieve my beliefs.
Please, help me to find my answers

We celebrate the birthday of Prophet Muhammad (peace be upon him). On this day, we read a lot of salutations on him and engage in a lot of prayers to Allah. We try to show our love for our Prophet (peace be upon him). How come you say we cannot do it?
 

What is sincerity, and what are the benefits of sincerity?

One of the guys at work was asking me why I became Muslim and I told him it is the path I must follow. I don’t know sometimes what I should say, for me it is the path I must follow. What can I say to someone; I don’t want to push what I believe, so how should I answer someone if asked, what is the right way to answer the questions? Sometimes I feel I don’t give the right answers... Any clues as to what I can say?

Which is more important: dealing with feelings and thoughts that Allaah dislikes, such as destructive envy, hatred, arrogance, showing off, thinking highly of one's deeds, hard-heartedness, etc., which form the evil that resides in the heart, or focusing on doing outward naafil deeds such as prayer, fasting and other acts of worship and fulfilling vows even though those other things are present in the heart? Please advise us, may Allah reward you with good.
