I just started making homemade baby food myself for my 6 month old twins. I researched a lot of baby food cookbooks and finally decided on "Blender Baby Food" (amazon link: http://www.amazon.com/Blender-Baby-Food-Recipes-Homemade/...)
I like this because it separates the food you can prepare by age and gives tips on meal plans, etc.
Regarding freezing, both this cookbook and advice I've heard from other parents is using frozen food is okay and you can freeze most foods (in an ice cube tray or I use plastic baby food containers) and thaw in the refrigerator. There are a few foods you can't freeze, like bananas, and the Blender Baby Food cookbook lets you know which you can/cannot.
The only thing you have to watch out for is this cookbook lists recipes with strawberries, tomatoes, etc. in it and some pediatricians recommend waiting until babies are a year old before trying out these typically allergic foods. I just asked my pediatrician, made a short list, and avoid those recipes.
Also if you haven't already, definitely get a baby food processor. I love mine "KidCo BabySteps Electric Baby Food Mill" - and a steamer or at least a strainer you can put over a pot to steam food.
Hope this helps!
