Is my design good enough in terms of noise and EMI as its 80MHz MCU board
Actually was looking into the same issue a while back:

Good clear guide from NXP http://www.nxp.com/documents/application_note/AN10897.pdf
Automotive introduction to EMI from Intel http://ecee.colorado.edu/~mcclurel/iap711.pdf
Another one from TI  http://www.ti.com/lit/an/szza009/szza009.pdf

Edit:
I don't really see any issues with the redrawn boards. Regarding the layout of Caps and header pins. see https://electronics.stackexchange.com/a/15147/15908
