1) How can I do research on aqaed. As I have heard a lot that taqleed is haram in Usool e deen. How can I do resarch on my own so that I can have my proof?

2) Please recommend some video series or books

3) Also, is there a book Or video in which all the views about a particular topic is presented because sometimes we are very much biased.

I recommend Ilahiyyat by Sobhani. He presents diverse views.

I also recommend out Islamic Beliefs series at hujjahseminary.com
