1. Yes, perhaps she has the Rinnegan but it was not shown. Infinite Tsukuyomi is a Rinnegan Genjutsu may be it is and I'll tell you why. Her Rinne Sharingan works like Sasuke's Rinnegan, If Sasuke can produce Amaterasu from his Rinnegan which is a MS technique without switching, perhaps she can do the same, may be she has Rinnegan in her Rinne Sharingan and she was able to cast techniques without switching. She may also have the Tenseigan but I guess Tenseigan requires more chakra as seen from the Last movie Toneri's Tenseigan fades away and he was not able to use it, so that's why she resorted to normal Byakugan and Rinne Sharingan (and yes plot restriction). The Rinne Sharingan is more Sharingan than a Rinnegan and so I think to cast genjutsu sharingan is required and to cast it on large population Rinnegan is required, and she had both in one eye.

2.The Rinnegan reflection in eyes could be because of Rinnegan, it is the main factor in controlling every person, similar case could be said for Nagato or Obito controlling people with chakra receiver and they have Rinnegan in their eyes, they can use its techniques and also for combined field of vision. So that is why everyone has Rinnegan reflected in their eyes during Infinite Tsukuyomi but here instead of chakra receiver its the moon that is channeling the chakra may be Sasuke's Susanoo was able to block it, he didn't get affected because as you said it got cancelled for him because he has Rinnegan.

3. My guess is that Sasuke's Rinnegan is because of Kabuto's Hashirama's cell probably they are modified along with Hashirama's chakra and his chakra plus some help from Hagoromo, the tomoe is due to some alteration in hashirama's cells just that's what I think :D, Kabuto's intention was to heal Sasuke and Hashirama gave him his remaining chakra, so his Indra's chakra + Asura chakra = Rinnegan and also he did meet Hagoromo because of that who split his powers and gave each of them his half powers. So he has eyes of Hagoromo, and I think Hagoromo also had those eyes with Six tomoe.

The tomoe thing is bit complicated though, in the series every time an Uchiha experience loss / separation from a person they gain some tomoe and when they experience death of person closest to them they awaken Mangekyou Sharingan. This could be because of build up of chakra, and every MS user could use yin yang release techniques such as Izanagi which is derived from Creation of All Things techniques which is a Rinnegan technique. And I believe the Rinnegan is somewhat devolved form of Sharingan and that is why Madara was able to switch it back and forth during the war, and also Indra's Mangekyou doesn't have tomoe but spiral pattern like a Rinnegan some similarities as we know Rinne Sharingan was once Rinnegan plus Sharingan but I think it has more of a Sharingan characteristics not just because of red colour but techniques like space time ninjutsu and genjutsu.

I have noticed in one scenario in chapter Kaguya's tears, her Rinne Sharingan tomoe (one set) disappears for some time and reappears when she says "I hate you", I think the tomoe thing definitely has some connection with the Curse of Hatred.

I have one theory and that is I believe Hagoromo had completely different eyes probably Rinnegan with tomoe and they also switch red/purple in colour and it was because of Ten-Tails, the Ten-Tails had some hate because she was sealed inside her sons and wanted chakra back so Rinne Sharingan is red in colour. After it was removed and separated we see purple colour Rinnegan without any tomoe. May be the tomoe has connection to nine tailed beast. The Rinne Sharingan was her from the start. One thing is always bugging me why the statue was screamin in agony was it so hurtful? Yeah Obito used one eye and he dragged a lot and he could have done that with both eyes instead of taking 100 chapters.
