[QuidQuoPro]

I would recommend that along with your Quran studies to start a course in fiqh/Islamic jurisprudence. This should begin with the fiqh of worship i.e. rules of Salah, wudu , hajj and so on and then move to other subjects.

Http://www.seekersguidance.org are running free courses in fiqh and I think you can choose to study the Hanafi/Shafii/Maliki madhabs. Also, you can also look into a simple course in Aqida which is best done alongside a qualified teacher.
