Truck questions

First of all I am going to do a tune up on the 97 Dodge 2500 I have. 5.9 liter( gas), 5 speed with 4 wheel drive. I need to know whats the best brands and such in everyones opinion of the following

Spark Plugs
Spark Plug Wires
Motor Oil (brand?)
Distributor Cap/Rotor
Antifreeze
Air filter or Cold Air Intake

Reasons why I am doing this; is due to the engine never wanting to run below 200 degrees, spark plug wires are loose, and I have no idea when the last tune up was.

Here is the next few questions; when I go to start the truck in the mornings or after it has sat for a while I hear a *clunk* if I push "to fast" on the clutch, is that normal? Also, after the engine has been running a bit, sitting still or driving around, I can smell what seems to be clutch, why is this?

The rearend howls unbelieveably loud so next week I am taking it to a friends garage to change the fluids and check everything over. Seems to be alot of problems with a truck I have only had the past month... :sad1:
