first tune-up

[debo4x4]

I am about to hit 30k in my truck.  I'm due for an oil change and I was wondering if there is anything special I should have the dealer check while it's there?  (I used to change my oil myself but I have a hook-up at the dealer so I get that, tire rotations and lots of other things for free) When do I need plugs/wires and any of the other small things that tend to wear?  Should I go ahead and upgrade to better plugs and larger wires?  I have had the oil changed every 3k and not had any problems with anything except the drivers side window motor was replaced(thanks to a forum topic a couple of months ago) and the usual knocking.  I have a FIPK in the garage but just havent had time to put it on yet.  Any tips or ideas?  Thanks in advance!
