Some interesting news

So, I decided to gather lots of my poems into one manuscript and try to get it published. I am also gathering together my random writings (paragraphs, essays, plain journal entries, etc.) as another manuscript.

Does anyone have any suggestions as to how I should arrange it? I was thinking of themes or chapters, but so far I have simply been going by the most recent date, and working backwards. Also, does anyone know who I should talk to about this? Any suggestions would be really nice to hear. Thanks everyone.
