How to move character along a spline with Blend Shapes and Triggers?

Hey there,
I‘m definitly a total newbie to unreal and not quite familiar with coding, so I got a few questions how you would build such a scene:

I want a character to move into left-right/top-down animations along a editable spline through my world.

Furthermore there should be an option to build in trigger points along the spline to cast different animations like get hit or interact.

How can I start building this Animation blueprints with working blend shapes?

Thank you so much in advance!
