Ibn sina,emanationism,the creed of the sufis and Ibn A'rabi?

Ibn sina believes two things wich are problematic to me: 1.that there is emanationism of Allah(aj) in creation like the neoplatonics,thru his single eternal act of self knowing wich is eternal. wich to me would imply that creation is eternal.wich to me is problematic and it also implies we are Allah,doesn't it? this also is used by ibn sina to explain why a absolutely one cause can create a multiplicity of effects,as philosophers like Vasubandhu have criticized this to 'prove'that Allah(aj)doesn't or cannot be the creator of the universe. 2.that all possibilities are realized necasserily by Allah(aj) he bases this on his understanding of absolute Divine simplicity. what is the creed of the sufis in regards to this(emanationism of Allah in creation,wich would make it eternal) and do the sufis follow A'shari,maturidi or ibn A'rabi in Aqeedah?what is Ibn A'rabi's stance on this,and what is his account of Allah's simplicity,his tawheed and his role in creation? I do believe in divine simplicity because to me it means absolute tawheed and vice versa,and I also am from a trinitarian backround with a latin eternal modalistic model so I was led to islam by understanding Aquinas,and taking it to the conclusions that his catholic presuppositions prevented him from reaching Vis-a-vis the Trinity. but I heard that al-Ghazali spoke against absolute divine simplicity?if I believe in absolute divine simplicity am I still a orthodox muslim?or am I outside the pale of islam?
