Joe,
Avast there! It's pretty simple. Yes, you can use the whole degree figures for Ap latitude (Assumed position latitude) Declination and LHA. But, to make it more accurate you should use the declination figure found in The Nautical Almanac which includes the degrees and minutes of the declination. Of course you could use the Ap latitude degrees and minutes and Ap longitude degrees and minutes (in the "Cos(LHA)" portion of the formula (cos(GHA - Ap longitude) also if you wanted. The same applies to finding azimuth with the Z formula.
