I hate asking for help with such a simple game but how do I get the blue bell from her sister?

talk to her and ask her about the dress. As soon as possible (she goes "bla bla bla") split and use your other half on your sister.
How do I get the burnt book? I've tried splitting, standing on the chest, then trying to stand on my own shoulders. It says I'm still not tall enough.
Stand on your own shoulders, then get the ashes. The hotspot is a bit further up, iirc.
When I try to stand on my twin's shoulders, it says "that would be a good idea if i were a little taller." I must not be doing something right.
Edit: Nevermind. I just had to right click on myself while standing on the chest. I'd been trying to split, then do the stunt.
