Yep, frequency ID doesn't even appear on some licenses. It's inconsequential.
Theoretically, there should be no Antenna #0. That is basically the antenna that's used at each location. Different figures may be entered for gain, directional characteristics (which don't appear in ULS or on the license, but are used for coordination), etc, but most preparers are sloppy and leave them each at 1. In theory, a Loc. 1, Ant. 1 arrangement with multiple frequencies would mean one multi-frequency base station, but in real life it's not usually the case.
MO = mobile, MOI = Itinerant mobile (no permanent location). This is a nationwide license and none of these frequencies are protected for primary status.
SC = special conditions. Click on the field and it will go into greater detail, for example, "Operating Nationwide including Hawaii, Alaska, and US Territories." or "Frequency Special Conditions
Operation on this frequency is on a non-interference basis to Canadian operations and you must accept all interference from operations in Canada. Licensee is responsible for resolving any complaints of interference to Canadian systems arising from operations on this frequency, including, if necessary, cessation of such operations."
Paging receivers are usually there if a site has no associated mobiles, but alerts receivers. Some agencies use the field to indicate the number of volunteer pagers, but most preparers leave it blank, whether they're there or not.
None of these appears to be licensed as a repeater - BUT - there was a period of time where low power repeaters were allowed to be listed as "MO" stations. So it might be possible. Being "nationwide" they can be anywhere, but they have to be on a non-interfering basis to site-based licensees.
You will not find tones on an FCC license. The FCC doesn't license CTCSS or CDCSS tone or code operation. That's between licensees to hammer out.
