To me, she sounds like the whole shedding experience has stressed her (not surprising really). The areas you say are left aren't ones that are going to kill her if they stay on (the crucial bit you have left is the eyecaps) so you're now in a position of weighing stress against the shed. Personally, if she's showing signs of stress then I'd give her a break for a day and try the eyecaps, then give her another break before trying the rest.
Also, if she's regurgitated water twice in a day, that means she's had a drink, brought it up, and felt the need to drink urgently enough to try again. Sounds like she needs to drink, so giving her a break will let her do that and take the water in before you stress her again.
