A garganta opened? I thought that was just Ichigo breaking through the clouds or the Shakonmaku or whatever from a first person PoV? And by Shinji saying that not many people can fight decently, I think he proposed that as Captain Commander Shunsui can't really get involved to directly maybe? Overseeing the fight and all? Mayuri and Urahara are sort of providing logistical/scientific/intel support and are not technically IN the "Wandenreich Shadow Area" they are in Mayuri's special lab thats sort of still in Sereitei by theory of dimensions and how the shadows work and that they couldn't turn it inside out into the Wandenreich so he probably can't sense either of them even though he knows they are there. As for Ukitake, we are all assuming/guessing hes not got that illness anymore, but Shinji doesn't know that, maybe his illness even prevents him from using bankai? Who knows, otherwise he would have said Ukitake can fight if he knew he would be of use, although he did forget Byakuya, Rukia and Renji, but he doesn't know they are back I don't think. Thats my reasoning for what he said anyway.
