For tensioners you need a pin for the tensioner and a set of solid mechanical tensioners. you have to take care not to mess up your cam timing.

If you want to do the chains, etc., you're into cam timing, you'll need dial indicator and the porsche fixture for it.
Cam tools for a 3.0 IIRC it could be a big nut for early cam or the later bolt on style camshaft. You need the year of the engine or just look to see what you have. There's two different tool sets for the two cam timing gear fastening styles.
Honestly for this task you need something like Wayne's book, as it has a good cam timing how to and all the timing specs.
