The 302 code flashing is indicating it is a true misfire and constant. The light flashes to tell you that it could be doing damage to the converter due to the raw fuel going into it.
The compression numbers are a bit high, if it's running rich then that could be carbon build up, however I would also try a different scan tool to see if the trims agree with what you are seeing, most systems top out at -25 and anything above that triggers codes so I suspect the numbers may not be correct, that happens sometimes if a scan tool doesn't read data correctly on a particular vehicle. One of the reasons why most shops have 2 or more scan tools, they all have odd quirks.
