I agree with everything Blt2Lst mentioned, excellent advice. I'd like to clarify, when it comes to the shop manual, make sure it's a genuine manufacturers factory shop manual, (in your case, Toyota). Don't waste your time, money or sanity with aftermarket manuals. They are far too general and at best, they're a joke. Also, as mentioned, the forum can be an excellent resource as well. Many members are certified technicians on one level or another. Some are factory trained, some are state certified, some are ASE certified and each has different levels of certification. On the other hand, there are some backyard, shade tree rookies too. Unfortunately, at this point, you're the one that needs to decide who to trust. As with most fields, there are no substitutes or shortcuts for knowledge, experience and hands on skills. After reading your textbook and the shop manual, you will be better equipped to distinguish the "men" from the "boys". Hope this helps.
