she starts crying before you even put her down for naps? sounds like you need to try to put her down earlier, before she gets to this point. i would try to stop the bouncing, her crib isn't going to bounce her in the night.
sleep training isn't going to be without crying, no matter what technioque you use. as least with pat shh you are with her the whole time and not abandonning her and can help her through it. it's learning process, she doesn't know how to do it and you have to teach her. that's all. the crying is just her voice, she's just saying her mom i don't know how to do it this way. it may take her a while to learn but she will.
if she is waking early for a nap i really doubt she's hungry. even a lot of newborns don't need to eat every 2 hours.
you don't have to try pu/pd for 45 min, you can stop and take her out and try to distract her until her next feed. this gets easier as they get a bit older...
when stretching her feeds out to 3 hours you can do it slowly, maybe aim for at least 2.75 hours, and don't feed before then. 15 min isn't going to make or break it. looking at your routine you are mostly feeding every 2.5 to 3 hours.
