Everybody has their favorite tools and different recommendations about what to start with. A scan tool is not cheap (for the 1994 and up model years), and if you have a friendly store that will retrieve codes for you, you might not need to buy one right away. For a lot of other repairs, well, you don't need a scan tool to tell you that your water pump is leaking or a head gasket is blown.
Personally, I would order the factory service manuals for your car; just use the form in the back of your owner'* manual. Those will have directions for _everything_ (even stuff like reupholstering your seats), and even if you don't want to do some repair yourself, you can loan the books to the repair place that does the work for you. (Make sure you get them back again!)
For repairs you do yourself, buy the tools as you need them. My favorite is Sears Craftsman, but others here may prefer Snap-On, Husky or other brands. Go with whichever is most available in your area and gives a good warranty -- hand tools in particular should be guaranteed forever.
In particular, buy a good torque wrench and learn how to use it. Practically every major component on the car has a specific torque setting for its fasteners listed in the service manual, and some can be damaged if not installed properly. In your case, I'm wondering whether the repair guys ever properly torqued either your cylinder heads or your brake rotors, since you seem to be having continuous problems with both. There is no substitute for doing something the way the car'* engineers say it should be done. Good luck and have fun...
