All you need is a crank puller and a BB tool. Easy as pie.
When I bought my first bike as an adult, I took it apart completely. Dismantled the freehub (that's right - geared!) down to the pawls and springs and everything. I was so frustrated I couldn't crack the sealed BB. My point is that relative to just about any other machine, a bike is as about as simple as it gets. Go for it!
