James,
There are some excellent books on race techique. The only one I have read, however is Principles of Race Driving by Ayrton Senna, but it is quite
good.
Of course, as Nigel says, there's no substitute to actually getting out there and having a go, but there is still a lot you can learn from the
books.
I wouldn't worry too much about handling and setup initially, as to start with the limiting factor will be your driving and not the vehicle (unless
it's miles out) once you feel that you could go quicker but the car won't let you then it's probably time to start mucking about. By this stage
you'll also have more idea what you're changing and why, you'll then have a car that you are confident with and understand. Remember, everyone is
different, what suits one driver may not suit another.
There's a discussion thread on this topic here that you may find interesting.

Another good scheme is to get to a couple of trackdays or even a race school and get professional tuition, it's not as expensive as you might
imagine and it worth seconds a lap. Plus it has the advantage of getting you out on a track while you're building your car or whatever, motivation
