The American Ephemeris and Nautical Almanac can be purchased from:

THE SUPERINTENDENT OF DOCUMENTS
UNITED STATES GOVERNMENT PRINTING OFFICE
WASHINGTON, D.C. 20402

You must specify the year you want.

Expert Software has a CD-ROM called RedShift 2.

You won't find any equations from either of these, but they will tell you the positions of the sun, moon, planets and stars.
I hope this helps. -Mike

A little late, but there are some books you might want to check out to assist with this sort of stuff:

Practical Astronomy with your Calculator, Peter Duffett-Smith (Cambridge University Press).

Practical Astronomy with your Personal Computer, Peter Duffett-Smith (Cambridge University Press).

Astronomical Algorithms, Jean Meeus (Willmann-Bell).

Spherical Astronomy, Robin M. Green (Cambridge University Press).
