an analog voltmeter works really great for checking all of those sensors. Just tap into the wires with a couple of 't' pins and away you go.

My MAF is reading about 1000 grams a second at idle, is that normal?

depends a lot on the weather, but yeah that seems to be in the right area. Only thing is if its off by 3-400 you'll never know but it'll cause some issues.
