I am considering converting to Islam and have several questions.

Is my name permissible, or should I change it due to it having un-Islamic meanings? Todd means fox, clever or wily (intending to be deceitful), and Christopher means Christ-bearer. I've been told that Todd shouldn't be used because of it's connotation, and Christopher is too Christian. Also, should I go through the legal change process or just use my new name like a nickname?

My next question is hair on men, my hair is long, it is past my shoulders but is neat and kept clean, am I commanded to cut it if I convert? My beard is already in and long. I've heard I should cut or not as long as it's neat. Also, what about piercings? I have lip and ear.

My last question is I still am researching and trying to clear doubts about Islam and converting, should I take my Shahadah now or wait and clear my doubts first and say it with a clear mind? I've heard some people formally convert only after researching a while. Thank you.
