Post Checking the Engine

Well I was hoping to clean/check a few things today, but last night it snowed so its a little bit chilly outside right now. Don't know if I'll do this today. Global warming betrayed me.

I was hoping to check:
-MAF
-Spark Plugs
-Cam sensors
(02 sensors were on my list but my friend told me that its a pain, and if something was wrong with them the CEL would be on.)

Why am I doing this? Well, I still have issues with the MPG, and just for the hell of it, I want to start learning. (Yes I'm a n00b. )
There's no CEL if anyone was wondering.
I do not know if the dealership did that one recall on that hose.
I already replaced the air filter.
I'm thinking about getting new spark plugs. NGK Iridiums.

Any tips, or suggestions are appreciated.

The cam sensors are really easy to check. I did it, and I am not mechanically inclined at all. What year is your car?
