So I was thinking when I can get it in there, they can do all of that, and adjust the derailleurs and true the wheels. And if the derailleurs still skip, get some new ones. How about the chain? That has to be worn out by now!
Sheldon Brown (RIP) site has good instructions on both, as does Park Tools web site.

You'll notice the use of some specialized tools for both. If you live near a bike co-op, you might be able to use their tools. I will admit to servicing bottom brackets and headsets back in the '70s using only a hammer and punch, and adjustable wrench. Being a poor college student and not having internet, etc. to show me the error of my ways, I used what I had. Not recommending it, just noting that it is possible. I would leave as much together as possible, i..e., don't remove the fixed BB cup, the crown race or cups on the headset, etc. Just clean them and repack with fresh bearings.
