From the pic that's an easy DIY job. Get a ratchet set and the best spark plug sockets are the magnetic holding ones at Autozone... no rubber spark plug inside boot holder that gets off inside the engine [hassle to get back out].
I called the Nissan dealership to get the price for a 105,000 mile service for my '04 Frontier King cab XE (4 cyl) 5 speed pickup and was shocked at the quote - $740.
Looking at edmunds.com maintainence schedule I got:
The dealer is giving me some spiel about how it costs $550 to change the spark plugs because the intake has to come off. What does this mean? I know spark plugs shouldn't cost more than $10/piece and the labor can't be more than 30-45 mins max., say even an hour that's $75-100/hr...where is the $550 figure coming from?
If it has the 2.5 engine, you do indeed have to remove the intake manifold. However, I don't think that engine was available in 2004, in the Frontiers. I think they're looking up the wrong year, or the wrong model.

My engine bay looks virtually identical to the posted pic with 4 wires on top going into the engine block. I have a 2004 Nissan Frontier XE 4 cyl and it has a 2.4 liter engine. 2005 Nissan Frontier was re-designed and has the 2.5L engine.
My concerns are:
How tight are the plugs screwed into the block? Do I need to use a lot of force to turn it? I don't want to break the plug and have a situation on my hands.
Do I need a torque wrench to torque it back up? I have torque wrenches but I haven't used them in years so they're probably out of calibration. I used to work on motorcycles extensively so i'm pretty good at these sorts of things but I have never worked a lot on cars.
Would I need a spark plug gapper to gap the new spark plugs?

Right. Methinks the shop quoted him a price for the wrong model, or year, of Nissan.
OP: I had a 1st gen Frontier for about 12 years. There is one particular spark plug that is a pain to remove. I'd recommend you look at web sites and message boards that deal with this issue. I have one website in mind but I don't think I can share the link publicly.
Anyways, I've heard that if you remove the hood it makes things easier to get to.

Hi EVAunit, are you sure it was a 2.4L 4 cyl engine and not the V6? The V6 has a plugs near the firewall I believe, looks like on my motor all 4 are on the top.

I had to remove the hood on my son's Nisan Frontier truck to get the plug, but that only helps a little by allowing you to put your left shoulder near the air intake by the windshield, and then stick your arm between the firewall and block to reach the spark plug. It has the V6 motor
