1) "I personally do not want to become a forensic pathologist because of the schooling and money". If this is the case, this pretty much rules out any other branch of pathology (which has similar or longer time frames for study) or really any other branch of medicine (which is similarly lengthy and expensive). That being said, I am not sure what you hope to gain by shadowing a Forensic Pathologists since you already know you do not want to do this.
2) Going to grad school essentially assumes a Phd track. This can take about as long as going to med school and doing a short (e.g. 3 year FM/IM or even AP only/CP only pathology) residency. At the end your job prospects are fairly poor given the state of research funding in the US at the moment. NPR did a nice series of articles on scientific careers in the US and it was pretty depressing.
3) PA is a terminal "professional" graduate (masters) degree. Job prospects generally appear pretty good, you can't offshore it, and the downside is that you stand for long periods of time, you work with dangerous (infective) material, and the career path essentially is either PA or manager of PAs (although I am sure there are PAs around who have gone into administration or some such somehow)
4) If you are undecided, a smart move is to change you chem minor to something business related (business, finance, etc...). If you don't know what you want to do or are prone to changing your mind, some more education on how business operates is not a bad thing. MBAs are common these days but a good way to get a decent job if you can stand the material. From my peanut gallery - the business of science/medicine is more lucrative and secure position the the actual performing of science or medicine.
5) Don't get career advice from randos on the internet. Talk to your guidance counselor or those around you who know you on strategies to narrow things down. If you want to shadow people, google for who does that in your town and just call them. Don't get hung up on technicalities like being affiliated with your school.
