Spark Plug and boot questions

Hi,
Went to the dealer tonight to get plugs and maybe boots tonight for my '03 V10. Plugs were over $7 a piece but after the sales guy saw the shock on my face he said he could let them go for $5.50 a piece. I said I'd think about it and left with just some oil.
I then went to AutoZone and they had 3 different versions of Autolite's anywhere from $3 to $6.50. Can anyone tell me what the recomended stock replacement plug is, and is one of the Autolite's the correct one? They had an Iridium model, a double platinum model and I think the other one was just a platinum model. Also, should I replace all the boots as well? The dealer told me the boots only come with the coils.

Am I being cheap? Maybe I should just get the ones at the dealer.

Thanks.

The "list" price on the plugs (at least in my area) according to my recent receipt is $7.11- my dealer gave them to me for$3.29 ea. I've only been in there maybe three times so he doesn't know me from Adam and I never asked for any special pricing. Didn't even think to check the receipt until later to see what I paid. Sounds like he did me right.

The boots are available separately from the coils. The part number on my receipt reads: F7TZ / 12A402 / AA
Not sure if all of that is the part number or if part of that relates to other info. They were $13 ea list, and I got them for $11.05 (That's $110.50 for the whole set - ouch.)

I bought a entire set of boots and springs off of Ebay for $30 plus $5 shipping. I have not installed them yet, but they really look to be decent quality, but time will tell. I bought them from this guy:

BOOT COIL ON PLUG SPP39 FORD TRUCK 4.6 5.4 6.8 SET 10 : eBay Motors (item 200409665818 end time Apr-22-10 07:50:15 PDT)

He says they are from Standard Motor company. Standard Makes a lot of OEM stuff for Ford and GM.

I bought my plugs at Pep Boys for $4.50 each. Boots around $10 each. I got Motorcraft...don't remember the part number, but Pep Boys has the correct ones. Boots were some other brand. Don't recall what it was, but it was gray in color.

Autozone sells the motorcraft plugs for $3.49 a piece...

I had to get some not too long ago when I had to work on a Madza 6. Triton engines and most other Ford or Mazda engines prefer stock Motorcraft plugs over anything.
