I'm to lazy and buzy right now.
You seems are familiar to PS pretty much. There is only one thing need to redone (reshape, repath etc). Shape2 layer's content.
If youou have not flatern shapes file? Then you allready have vector kinda file. If needed eps file then export all path (from shapes) to Illustrator and combine together.
1. Find original file where shapes aren't merged together (you can set shadows to each, no need for merging). If you don't then that need to redone as shape. And text as text (that you allready have).
2. Save as.... choose Photoshop EPS.
