You can find answers to a lot of specific questions just by googling "Whole30 " & whatever your question is - i.e. "Whole30 can i have canola oil"
Here are some blogs I really like for recipes/etc:
http://theclothesmakethegirl.com/ - I used her Week 1 & Week 2 meal plans and I LOVE her Greek beef stew and chocolate chili
http://nomnompaleo.com/ - If you get the chance, you should hands-down make her Cracklin' Chicken - I wanted to eat the entire batch in one sitting
http://primalbitesblog.com/ - primal means she eats dairy, so not great for Whole30 but still a lot of Whole30-friendly recipes. I really like her Hearty Fall Frittata, and she has recipes for both Buffalo Chicken Meatballs & Paleo Buffalo Wings
http://againstallgrain.com/ - not great for Whole30 - she's more focused on gluten-free and tends to recreate a lot of baked goods and breads
