Quick, simple spark plug questions

Hey, all. I'd like to swap out my plugs for some iridiums, but I have 0 experience with working on bikes as this is my first bike ever. I'd just like to know:

1) I've seen a couple of different model models listed in the verses; which one should I get?

2) Other than the plugs themselves, are there any other small parts or anything that have to be replaced when replacing the plugs?

Thanks a bunch in advance guys!

ngk-7803 Locally I can get them here at Advance Auto or O'Reilly's
They may have to order but it usually only takes a day or two. If you order by the 7803 number for some reason they come up cheaper (about $6 a plug) but not bad since they will probably last the life of the bike.
They usually come pre-gapped at .32 but a quick check never hurts. All mine were just fine out of the box.
Also, be sure and use a little never-seize when you install.

Thx for the info, Dianna!

Oh, you've reminded me of another question:

What's the deal with the "gapping" I keep reading about.

Gapping is measuring and adjusting the size of the gap between the spark plug electrodes. Having too wide or too narrow a gap will mess with performance.
