Yes.
Yes, you have to compress if you remove either.
if you are talking about those rubber springs yes! if they are: the new struts should come with a bolt in the box which you use to keep the rubber spring compressed. the springs have a threaded insert where the bolt threads in. if you don't good luck getting that rubber spring to compress again.
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
You need to remove the head to do this . Then compress the spring and remove the keepers
