Unless the artwork is larger than 227" X 227" I design it at full size and output it that way without any scaling. If the artwork has any raster-based elements in it then I choose a PPI setting that isn't going to bog down the computer, but still look good. 72ppi works pretty well for most large format printing purposes (vehicle wraps, outdoor signs). For displays viewed closer, like a movie poster one-sheet, 150ppi is good.

We for the most part use EPS files for our printing files. Looks like you guys are more for the PDF files. Is that for better quality? My thoughts they mainly used ESP was because it's vector based (and I thought would stay more true with everything) please help enlighten me on this subject. Thank you in advance.
Are you trying to imply PDF does not support vector-based artwork?
The decision whether to print using EPS or PDF files kind of boils down to the RIP a given shop is using and what features that RIP supports. Generally, I use PDF more often because it tends to be more reliable at outputting the latest bells and whistles from Adobe Illustrator (things like transparency effects, free form gradients, etc) as well as all kinds of "floated" raster-based artwork with transparent/clipped backgrounds.
