Just don't forget the 100nF bypass caps.

On that note. A bypass cap just needs to be nonpolar, correct? If it is mylar not polyester would not cause any issues?

Mylar is another name for polyester film,specifically biaxially-oriented polyethylene terephthalate or boPET. Dupont's name for this product was trademarked Mylar.
