Does this come with all the necessary cords to connect this to a computer? Is it rca trs or xlr?

It depends on which speakers you order. The 3.5 and 4.5 come with everything necessary, but the 5 and higher definitely do not come with everything you need. Just the speaker and AC adapter.

Is the the Presonus E3.5 woofer speaker cone unprotected? It appears to have no fabric covering as many speakers would have.

Take a piece of t-shirt and bring it back and forth between your face and the monitors.. you will hear that even something like a tshirt of pantyhose, has a considerable effect on the sound projection. Also, having grills on the speaker looks cheap imo..

I am a Motivational Speaker, can I use these with a microphone when speaking to an audience of 75 people?

There are better choices for that -- you want speakers with a built-in mic preamp, and probably higher wattage amplifiers. You may also want folding speaker tripods. I suggest you puchase speakers designed for this, with a tripod screw hole on the bottom, and XLR mic inputs. For example, Bose EONS sound amazing for music as well. You may also wish to purchase a good wireless mic. Think of it as a system. The size of the room and the audience determine the required size and power of speakers.

Do the Eris 4.5 mute themselves when a headphone is connected?

Ideally they should, unless you’re using the Presonus Audiobox (or any other audio interface) and you connect headphones to that. In which case, they won’t mute.
