buy  a Chilton's manual for your car. it is not the best auto repair manual,
but a good place to start with routing maintenance stuff.  You can find them
at any auto parts store for just a few bucks.

Next find a friend whom has done some car repair work to watch over your
shoulder and offer tips.

Get a decent set of tools from Snap on or Sears or something. Deep well
sockets are a must along with extensions for ratchets, also get some good
wrenches, screw drivers, and torx bits. Don't go cheap on tools they just
break and strip bolts and nuts.

Some of my tools are 40 years old and still work great.
