Maybe try searching for that model name, year and .pdf in the search, chances are you will come across the service manual.
I would think that top cap assembly would come apart and you could pull the spring out the top. If you have to pull the whole fork apart it's probably not super hard. To pull the lowers with a Rockshox you generally unthread the bottom bolts about half way and hit them hard with a mallet. They will pop the damper rod things loose from the inside on the lowers and you can then unthread them all the way and pull the lowers.
You would need snap/retaining ring pliers to pull the internals out of the upper/stanchions at that point. I could be totally wrong about that, but that's how they have been held together forever.
