The higher your flux density, higher standby loss in the core; a lower flux density of 1 Tesla (10,000 Gauss) has been suggested by others here as a optimum value to keep core losses to a minimum.

To calculate the turns required for your core This Calculator  allows you to input the core cross section area in cm^2, mains frequency and number of turns. play with the turns value to get the required flux value.

For copper wire size, aim for 4 amps per 1mm^2 area; then you can see if that size wire will fit on the core, compromises may have to be made to get everything to fit.
