Actually, Barnetts Manual takes you from being a total newbie to being able to tackle anything as long as you have the right tools for the job. They even recommend the best tools out there to do the job and pull no punches in doing so.

You can do a lot of maintenance on your bike without specialized tools. There are some areas where they are indispensable. I wouldn't go out and spend $600 on a bicycle toolset either. Most of the tools are for bikes you don't own.

Get specifics like cone wrenches, bottom bracket tools, free wheel tools, and crank pullers for your specific brand/type/size of bike components. It should be a while before you will need these.

Generic tools are 4th hand tools, 3rd hand tools, cassette tools, and cable cutters. You won't need these very often and when you do, you will. It will be a while before you need these.

A basic set of 3/8 inch drive hex head metric sockets, 3/8 inch drive 6 point metric sockets, a 3/8 inch drive ratchet, and a 3/8 inch drive torque wrench will get you pretty far. Don't forget a pair of small flat head and phillips screwdrivers either. You should get these now if you don't have them already. Everything but the torque wrench you can find at Walmart for $20 or so if money is an issue and you don't mind "Made in Taiwan" stuff. Craftsmen stuff from Sears will set you back more, but less than a hundred if you shop smart. SnapOn tools will set you back several hundred dollars just for the above.

Torque specs for bikes are in inch pounds so try to stick with a wrench that handles up to 600 inch pounds - unless you want to always be multiplying foot pounds by 12 to get your value. Park has a couple of torque wrenches - a 3/8 inch drive and 1/4 inch drive that work fine. Nothing fancy, but they are around $30 each or so. Also, they have 3 crowsfoot wrenches that work with the 3/8 drive torque wrench for headsets, pedals, and cranks that you should get to do the job right. Most of the problems you read about from clicking bottom brackets and such are from shade tree mechanics who don't use the proper tools.

Not every maintenance procedure needs to be done at the same time. Buy the stuff as you need it.

The first thing I would get is a good chain cleaner and some lube. I use the Park chain cleaner every couple of weeks or less on mine. Keeping your chain lubed and clean is the most important thing to do on your new bike to keep your drivetrain healthy.

Hope this helps.
