Where can I purchase the best tune up components for my 2003 XE Frontier?

I need some good advice...

I am the original owner of a 2003 Nissan XE Truck [4 cylinder]. Recently the truck just past the 100,000 mile mark. It's running a little rough lately.

I am asking for advice as to which brand parts to use for a tune up [plugs, rotor, dist. cap, etc.] and belt replacement [3].

Can someone help me make an educated decision on this?

I went to Kragen's today. Just wondering if Auto Zone, or Napa would be better.

Any help would be greatly appreciated.

Have a nice day and Happy New Year everyone!

They basically sell the same brands. Napa is way more expensive. Rockauto.com seems to have the best prices. I've never had a part fail except for used stuff I have bought in the forums.
