For ears, another vote for Sordin and for SRS Tactical. I am using the Supreme Pro-X and they are excellent, not cheap but well worth it to be able to hear range commands, squib loads, etc. while preserving hearing. One thing to keep in mind especially if you are shooting rifle is depending on your head, stock, etc. the bulkier ear muffs can interfere with your cheek weld. The Sordins are reasonably slim.
I wear monovision contacts with the dominant eye set for the distance to the front sight, so I can use various safety glasses, currently Revision SawFlys which have clear, yellow and green tinted lenses.
Depending on the type of shooting you might also consider wearing a hat with a brim to keep brass from falling behind the glasses - I was ROing an IPSC competitor a couple of weeks ago and he had a hot shell casing bounce off a wall and stick behind his glasses, not very pleasant.
Finally the hat, glasses and muffs need to fit and be comfortable together, certain types of glasses can interfere with muffs, some muffs don't fit under certain hats, etc.
