The Torpedo and Crack will teach you wildly different soldering skills. If you see yourself building one-off tube amps using point to point techniques, the Bottlehead is a good starting point. If you want to do primarily PCB based projects, the Torpedo is better.
It is probably a good idea to get one project under your belt before jumping into future ones.
Different people learn differently -if you are a book learner, Art of Electronics is excellent. If you are a hands on learner, start soldering working on other people's projects, and trying to trace what's going on. It is how a lot of us got into this stuff.
