You're so definitely not on your own!!! I really think sleep is the hardest thing about being a parent,both trying to teach it,and ensuring you get some yourself too!! My ds is now three on sunday,and despite teething,potty training,HUGE tantrums,phases of hitting etc,I STILL think sleep is the hardest thing!!!! To be honest I'm not an expert on pu/pd I can only tell you what I'd personally do myself. I think when you're teaching a baby a new sleep technique you're going to get at least some sort of resistance as they're obviously wondering what's going on,so go with the flow with her getting frustrated. This will definitely lessen as she gets used to the new technique. If she's arching her back I'd put her down then assuming she still crying (probably likely) I'd pick her up again straight away. I'm not sure if this is actually the recommended advice but I found with ds it's simply impossible to manage the weight of an angry baby throwing all their weight back,and so I just HAD to put him down!! The nap times sound good to me,at this age ds had a day that ran 7-7 and slept roughly 9-11, 1-3 and had a short catnap of around 30minutes sometime around 5. Those times are post-sleep training though and so do include time for him to settle himself-i.e. I put him down awake in his cot at 9 so'd probably be asleep more like 9.20 so I guess they were roughly 1 1/2 naps. Anyway,I'm rambling now,let me know how you get on.
