I want to use switches on pins A0/14-A5/19 and put a POT on A6.
I am using an old style NANO.
The true issue is I already wired it up and don't to move and change bunck of wiring.
I heard if you use one of the 8 analog pins for AnalogRead you can not use the others for DigitalRead. is this true?"
If so I will write it read analog and convert it in the program.
any thoughts or tips welcome.

No. Why didn't you just try it?
But A6 and A7 are not available for digitalRead() because they are analog inputs only.
I've play with this stuff for a while now and i though i hear if you set up the analog set of inputs as analog the all are analog. I was hope some one could confirm it true or false. I'm at work and tonight I can't try it and it was eating at me.
False.
You asked "is this true?" and pylon said "no". You already had your answer 
The pins are all independent of one another.

Pins A0 to A5 inclusive are fully functioning digital pins. A6 and A7 are not, they are only connected to the ADC input multiplexer so can only be used for analogRead(). There is no restriction in using A0..A5 as a digital input, digital output and analog input, all the hardware is independent so you can do all three at once if you wish (!)
