Simplify artwork

I have created a crest that I eventually want to make a compund path, one color, and no fill. There are paths and lines and white objects, as well as transparent objcets in this. After and if I get approval to proceed I will need to make it a simple compound path in one color to print on shirts, etc. 

My question: is there a simple...couple of steps to do this, or do I have to select each object and cut out the white parts and convert the lines to outline, etc to get this in the final form I need?

I guess I could go to photoshop, select the black and convert the selection to a path, but I'm afraid I will loose detail that way. It can be done step by step, but I'm an old Illustrator user and probably am not up on more recent capabilites. That is why I am asking.
