But it's not exactly rocket science either, so if you have even marginal mechanical ability you should be just fine.
Here's a great tutorial:
Pedro's DIY
Pedro... thanks again, man. Can't say that enough.
I used the Bosch plugs and they work great.
You don't need to jack the front. You can jack the rear one side at a time if you like.
Don't disconnect the battery. Why would you have your alarm set while you're doing this anyway?
You do remove the coil packs from the plugs (obviously) but I see no reason to disconnect the wires from the coil packs unless you are replacing them.
Before you start, look for oil leakage from around the tubes. Might as well replace the o-rings while you're in there if they are starting to seep.
I like that duct tape idea. Cross-threading plugs is bad.
I don't use a torque wrench. I tighten them until I feel the crush collar compress. Been doing plugs that way for 30+ years and never had a problem. If you don't have that feel then you should probably use the torque wrench.
Set aside the afternoon to do the job. Sure you could probably blow it off in an hour or two, but relax and take your time. Have a good look around in there and enjoy the process.
