Problems come in three's..right?

Hello everyone! Well, I am having some problems with my 98 Dodge Dakota Sport 3.9L V6. Problem A. My catalytic converter is making a rattling sound. B. My upper and/or lower joints on my front left wheel is making a bad clunking sound when I turn my wheel and when I stop. I feel the car move on my steering wheel when I turn it. C. My break disc on my front left wheel is worn down. Basically, I am looking for suggestions on repair manuals to see if I can fix these problems my self. I’m not sure how hard it will be to change these parts. So if you think it would be to hard for a beginner just let me know. I appreciate it!

Well, there are chiltons and haynes manuals that are really good. Brakes are fairly easy to do, but catalytic convertors aren't. The clunking might be ball joints, and they are a pain also.
