One thing that I did want to know; however, was would I be able to say take of my current crankset and install a new one if I wanted to, on my own or would special tools be needed that would probably require me taking the bike to my LBS?
If your cranks don't have self extractors(soras don't), you need a crank removal tool.You'll need a different BB when upgrading form sora to shimano octalink,and BB removal requires another tool.
