Gluten-Free Living Magazine has been a great source of information for me in the eight years that I have been diagnosed with celiac disease. They have done a lot of work researching ingredients, which was especially helpful before the food labeling law went into effect. On their web site they have a Gluten-Free Holiday Guide which discusses different categories of holiday food and provides a few recipes. If you’re unsure about eating during the upcoming holidays (and even if you’re not), you might find it very helpful.
If you have a question about a recipe (especially substitutions and nutritional information), please read my FAQ page before asking the question in a comment.
