If so, you have two options you could try -
1. Locate the power switch on the mini PCB board & trace the two copper tracks leading from it to the header on this board. If you can see which 2 pins in the header the copper tracks lead to, you should then be able to figure out which of the 2 wires in the ribbon cable these correlate to. Follow the wires to the other end of the ribbon cable & this should tell you which 2 pins on the motherboard header are used for the power switch.
2. Test every pair of pins in the motherboard header by connecting the power switch connector from the new case to them. I believe you said you had already tried this method once, but remember that the 2 pins may be either in a line (on a single row) or spanning across both rows (assuming the header consists of two rows of pins & not one)

Would it matter what angle I plug the Power/Reset/LED plugs into the pins? Is there a positive and a negative? If that is the case then my number of configurations doubles, and this will be very difficult.
If I do get it to work, how should I mount the Motherboard Header in my case? And do you think it will need to be properly grounded?

Firstly, you shouldn't need to use the seperate header at all. You should be able to simply connect the case connectors directly to the motherboard (i.e. without using the ribbon cable).
Secondly, the switches (power switch & reset) have no polarity - they can be connected either way round. LEDs however do have a positive & negative and will only work one way round.
As for the USB - I don't recommend stripping any usb connectors apart.
If the front panel usb on the old case (which i assume is also mounted on the seperate PCB board) connects to a USB controller header on the motherboard, AND the wiring spec is standard, then you should be able to connect the new case's front USB fly lead to it.
However, you must be 100% certain of which wires connect to which pins in the USB header. Getting it wrong can fry the motherboard.

Motherboard>Ribbon cable>Header>Ribbon cable(Larger pins)>"Power panel"(With Power, Power LED, and HDD LED
Right now I am set up like this
with the wires for my front panel rearranged and working on the cradle with the larger pins that would hold the ribbon cable going to the "power panel". It is operational, and I am confident in the job I have done. But now I would like to try connecting the USB cables from my new case to the header(which housed the front panel USB ports on my old Dell case).
