You are on the right path. Put the body of the bolt in a padded vice and pull the bolt handle back until you can drive the firing pin guide pin out leaving the punch in place. Remove the firing spring plug and then pull out your punch putting a gloved hand over the hole to capture the firing pin spring.
Going back you need to compress the spring with anything that will go across
the spring yet fit inside the bolt. The right sized flat bladed screw driver works best. I made up a tool on my lathe from an old piece of aluminum cleaning rod by cutting a shoulder a slot for the pin to pass that barely fits inside the spring and yet goes into the firing pin. The spring while stout is no big deal compressing, it is getting the pin started and keeping the spring behind it can be a bit challenging but if you have the flat blade of screw driver flat to the pin you will have it made.
