Today i'm going to do a compression test, and i would like to know what numbers i need to be looking for. Also do i take out just the T or L plugs and run the test what do i do there?

Trailing and Leading have nothing to do with it.

You have to test the front and rear rotors, each rotor has three compression strokes.

I forgot the correct psi that it should be, but do a search it's been mentioned before.

Generally speaking, 90 and above is fairly healthy. Numbers closer to 100 are preferred. Numbers less than 80 mean you're in for a rebuild.

Yeah, i'm 80 in the rear rotar, and a big 0 in the front rotar, i took a little mirror and you can see that the Apex seals are fucked up, and one of them is totally cracked in half, so thanks for the help

Where did you get a compression tester for the rotary?

Thanks

You generally don't really need the rotary compression tester.

If you're quick enough to tell the minimum and maximum compression on your gauge that's usually sufficient.

All the rotary compression tester does is give you a nice printout of peaks and valleys so it's easier to tell the min, max and difference.
