If you don't buy the actual book you could answer most of your list for tools by spending time going through the Park Tools Repair pages picking out the procedures for the components you'll be working with. At the same time you read and look at the pictures for each major area you can at the same time evaluate if it's something you'll be comfortable doing yourself or if you would rather have a shop do the step and how much of it they should do. The Park pages also show and list the tools used for each component.
