Just picked up a 2003 F150 4 door Lariat Triton 4.6

Really enjoying the truck thus far

Before I get too many more miles on it, I want to do some maintenance to it. Powder its nose, so to speak. Handle anything that might need attention, get all the maintenance done. That way, I know the truck is 100%.

But, there's a slight problem, I have Zero experience with Ford Trucks.
The closest experience I have is riding in my buddy's Explorer a few times.
Other than the basics, like plugs, fluids, filters, I don't really know where to start.

So, I'm hoping to enlist one of you Ford Guru's to help go over my truck with a fine tooth comb and help identify any potential issues.
(no problem compensating for the time)

I'm completely open to any advice I can get. Anything from what spark plugs to use, to what fluids, to things I should check out/test, to common issues to keep an eye out for, all the way to good advice on some goodies.

Greatly appreciate it.
