-->Should I not be working in the Adobe RGB color space because I'm on a PC?
The choice of a working space has nothing to do with the operating system!
-->Or should I say, is it smarter to run at 2.2 6500k sRGB until I transition over to MACs?
The TRC gamma and the white point of the display has NOTHING to do with the TRC gamma and white point of your working space. You can use whatever working space you wish! That being said, Mac users should calibrate the TRC gamma of their displays like their PC brothers (2.2). But again, this has nothing to do with the RGB working space you edit your files in. With a good ICC profile that describes your display, you can work on either platform and produce the same color appearance from the same working space.
-->d strange results with different labs. Either the photo looks like it was printed in sRGB from an embedded Adobe RGB color space or it's always 25% darker in the actual print than on my monitor.
The issue was the lab isn't color managed and when they got a file that wasn't in sRGB, their heads exploded. With someone that is working properly with color management, you can hand them data in either sRGB or Adobe RGB and they will properly convert that data to their printer color space (NO output device other then a display can output sRGB).
-->They claim that no matter what color space you submit your photos in (adobe RGB, sRGB) they will properly convert the image so no prior conversion is needed on the photographers end. I was skeptical from the start when I read this, but simply didn't know enough about color management to turn away from their services. Me and my wife prefer to work in Adobe RGB from the camera>photoshop>to print.
You need to have a conversation with them and see if indeed they do use proper color management or simply tell you this. Most Frontier labs want sRGB because they are too lazy to setup the machine to work properly with true output profiles so they want data in sRGB so the system can simply assume that all files are in that color space for the eventual conversion to the print color space. That CAN work but it's not ideal and if they are doing this, giving them a file in Adobe RGB will produce quite unacceptable color output.
-->if I drag an image from the Adobe RGB CRT over to the sRGB LCD...
I seriously doubt you have an Adobe RGB (1998) CRT so you need to clarify what you're referring to. There are about 500 such displays in the entire world (I have one) and they cost more than most cars.
You might want to read the following article (it's general enough that much of it covers some stuff you're talking about, just ignore the stuff about the E1):
