What are the comfortable ranges for oboe and EH?

I'm an amateur composer and I'm writing a piece for two oboes and English horn, and I worry that I'm making some of the notes too high for non-professional players. I also worry about the oboe's low range, but with the EH there I don't have to use it very often

Also, how fast is too fast for repeated staccato notes? I know double tonguing isn't a thing for double reeds so it's more difficult. Is eighth notes at dotted quarter=130 (quarter=195) too fast?

Thanks!
