When the pedal goes from slow to full speed, it just needs the capacitor replaced with the thermal switch. That thermal switch is a free item that you can get from your Bernina dealer, and is very easy to install. Some pedals have the thermal switch AND the capacitor. If that's the case, you just cut the capacitor out and leave the wires with the thermal switch.
The bobbin case latch gets bent at the small curled end. If it's not too bent, you can put it back together and keep using it. If the latch pops off every time you use it, you should probably replace it. Looks like you've got all of the parts.
I wish you were in my neighborhood. The old Bernina 8 series are my favorite machine to service!
