Measuring resistance with multimeter

Please excuse my ignorance regarding multimeters and electronics. I'm in the process of trying to learn about all that stuff.

I need to test a 1M ohm resistor to confirm that it's working.

Apparently the multimeters I'm considering buying are manual range. So to test a resistor I would have to turn the dial on the multimeter to one of these settings: 200, 2000, 20k, 200k. But some multimeters have 2000k and some have 20M. Does that matter at all for testing a 1M ohm resistor? If so, which is better? I don't think I need an auto-ranging multimeter. That would probably be a little over the top for my needs right now.

Does it matter whether the input impedance of the multimeter is 10M ohm or >1M ohm? Or does that not have anything to do with testing resistors? That has to do with voltage, right? This stuff is so confusing.
