If you do, you may get lost, run out of fuel, or both. Best thing is to use an Excel spreadsheet for flight planning, then updating for the winds is easy. You can find a lot of these on the internet.

How do I find My True airspeed and RPM setting in the POH, I know how to interpolate but I mean taking the temperature from the metars and using the ISA which I don't understand.
Better to use the winds aloft forecast. The actual decrease in temperature with altitude will rarely be ISA.

When I use my flight computer to determine my Ground speed do I set the minature hole over 100 and than slide the mark I make with the pencil to my true airspeed?
That would be physically impossible. Or should be. You slide the TAS up and down (not rotate). The hole will end up wherever it ends up. It will show your GS.
