So I'm trying to trace down an idle issue I'm having and wanted to check my TPS readings.

So am I checking it correctly:

Pulled it off the throttle body off the car to make it a little easier to get to.

Set MultiMeter to 20k ohms.

Place positive lead to where blue wire would touch

Place negative lead to where black wire would touch

0.95 with the throttle completely close
3.66 with throttle completely open

It should be closer to 0.5 closed and 4.9 open, right?

What can I do to correct this?

Do you know the difference between ohms and volts?

I should have measured in volts I guess, right?

You can test a TPS in either ohms or volts. You just need to know what they should read in which ever unit you are measuring and the procedure for measuring each one.

Ok. I get my setting correct on my multimeter.

Here's what I got:

throttle closed: 0.56 Volts
Full open: 4.63

Does that seem about right?

That is about right. The 4.63 is a little high for a stock TB unless you have ground the WOT stop. Those voltages should not be causing any problems.
