You've gotten some pretty great ideas. Learning to use coupons effectively has helped us so much. As far as dry goods etc., go if you don't already I would find ways to put those items that are boxed into better packaging, like glass jars, etc.
I have found that loaves of bread and shredded cheese freeze really well.
As far as food goes - what about mixes? There are some great books you can probably find @ your local library or used book store that have mixes for breads, etc. You can make these ahead of time (somtimes as much as 6 months) and use as needed for a variety of meals. For instance I found this
Make a Mix Cookery
book locally for $7 and it's got some great ideas. I also have another one from the 70's that focuses on great ideas for freezing foods.
Another idea is making food ahead of time and freezing it in the pan you'll use to cook it in - for example making lasagna ahead of time, lining the pan with foil - layer your lasagna as normal. When it's frozen, take the food out of the casserole dish, wrap it however you normally would to preserve it in the freezer and save it for whenever you need it. Even making pancakes and waffles ahead of time is an idea. Freeze them and then toast them as needed.
Also there is a great thread about feeding the freezer here on mdc:

ETA: There are also alot of great meal plans online for food storage - or just general info about what is needed for food storage. If you're looking for general amounts - there's a storage calculator online I think that gives you amounts for a year of general food storage stuff (according to LDS standards) - and you can adjust it as needed for your situation.
