Here are a couple that I use:
Menus4Moms http://www.menus4moms.com/kitchen/weeklymenu/2008/080630.php
There is also a meal planning calendar you can print out, and it has a column for grocery list and for notes to help you plan out the meals.
I also signed up for Arcamax, but those recipes tend to be more gourmet style. However, there are weekly recipe plans. The most they do is send you advertisements, but I just delete them. www.arcamax.com/recipes
For quick, free recipes to help you out, I use www.allrecipes.com and I look for things based on ingredients I already have and look at the reviews written.
I'm sure there are more, and I look forward to seeing the suggestions others have.
