I don't see any set up details. How is this installed? What does it connect to? How is it mounted?

It simply has N-Female connector which would connect to your 50 Ohm cable with appropriate connector. Purchase includes bracket for installing on any pole but the mounting pole itself is not included. If you don't have anything to mount on, and need a pole to mount, it must be purchased separately.

Here's one pole: https://www.signalbooster.com/products/j-pipe-for-antenna-pole-installation-19-inches-fully-adjustable

I purchased this antenna a long time ago and just opened up the package. There was no mount included. Is there any way you can point me to be able to purchase them? I realize it's been too long to get reimbursed, but am having a hard time finding the exact mounting hardware for this antenna. Thanks.

Correct, this antenna purchase does not include a pole to mount antenna. We carry many poles and brackets to mount antennas. You may consider J-Bar Pipe which includes hardware to mount pole to wall, etc. and you may consider L-Bracket and U-Bolt to fasten antenna to the pole.

So a coaxial cable runs down from antennae and connects to a WiFi receiver (modem). But there's no coax connector (female)... only ethernet jacks. How will that work?

Some modems have an open antenna port marked, "Coax" and for some you would remove the whip antenna or right angle antenna from the router or modem and connect the coax cable coming from exterior antenna there.

This antenna has N-Female connector so you would first need a cable like LMR400 with N-Male connectors (whichever length you need to reach your modem or router).

Then you may need a N-Female to SMA-Male connector or N-Female to SMA-Female connector or similar to match whichever your cellular or wifi modem/router antenna port has got.

This is how you're basically replacing your underperforming cellular modem or router antenna with a more powerful exterior antenna which can catch signals better from outside, instead of interior stock antenna trying to catch already degraded signal inside (degraded due to building structure that blocks signals to cellular modem) for the modem to stay connected consistently and broadcast signals strongly across your living spaces indoors.

What indoor amplifier do I need?

You can use this as a passive antenna by connecting cable from it to your own wifi or cellular modem which requires boosted signal.

No signal amplifier is required in between.

However, you can use one if you want a powered amplifying system.

There're too many in the market to list here - practically any wifi amplifier or cell amplifier can work with this antenna because it covers both wi-fi network 2.4ghz (2400 MHz) and mobile network frequencies 698MHz to 2700MHz.

Please note that all cellular amplifier kits come complete with exterior antenna but you can choose to switch it out with this one as it may offer higher Gain at 10dBi, than the stock antenna that comes with most cell phone signal booster kits.
