Rik,
You will be better off with a 2008 Nautical Almanac for your 2012 trip. This way the Sun data is close enough as is and the GHA of Aries needs to be adjusted by adding 1.8' minutes of arc. Sunrise, sunset, twilights, and Sun meridional passage is good as is also. Polaris and star SHA/Declination can be photocopied from a library Nautical Almanac for the current year and inserted in the 2008. Amazon.com has good deals on out of date Nautical Almanacs. $8 should get you a hardcover copy in very good condition for 2008. Geoffrey Kolbe's Long Term Almanac is a great option and is good to the year 2050. Check Amazon for a paperback copy.
