Can someone help me with finding out about the main types of dhikr in the Qadiri Tariqah?

why don't you search for authentic thikr, from Sahih hadeeth instead ?

According to me the Best Book to refer for El Qadiri Zikr is Al FUYUDAT EL RABBANIYAH , i perform everday Zikr from this very book . It is been translated by Mukhtar Holland, and publication El Baz .

It has many Dua's . InshAllah u will surely benifit from this book.
