1. The ritual your speaking of was Jiriaya gathering Senjutsu chakra, shading under his eyes would allow him to summon the sages without having to move. Neccesary because he would have turn to stone if he had done so.
2. Even if we assume your correct, Ma and Pa would have surely told Naruto about any special requirments to summoning them in the time he spent with them. Especially when they were summoing Naruto.
1. No, gathering Senjutsu chakra requires the user to stay completely still, Jiraiya was able to move around while only keeping his hands tied together, which means he wasn't gathering Senjutsu chakra, but instead summoning the two sages ( which Jiraiya even mentioned he was doing ) in order to automaticaly sustain SM for him.
2.
"Would have surely" means nothing if we haven't seen it on-panel.
Furthermore, even if Naruto were to know the ritual, it would still take longer than the Kirin preparation, so it wouldn't have made a difference.
