I try never to freeze more than I will use in a year. Each year I freeze (and this just went up due to Logan):
3 flats of strawberries (about 12 gallon sized bags, at 1-2 high)
25 lbs of blueberries (about 20 quart sized bags, pretty full (4 or 5 deep))
25lbs of broccoli (about 9 gallon sized bags, blanched and cooled, then frozen)
30lbs of green beans; I buy a case (about 12 gallon sized bags, blanched and cool then frozen)
4lbs of snap peas (1 - 2 gallon bags... this is what I did last year. This year I am putting them in quarts. So it should be about 4 of those.)
20lbs of beets (topped, blanched and frozen, this makes about 5 gallon bags)
I try to use these in one year. We haven't failed yet... although every now and then we have a left over blueberry bag or two.
Bread: I buy at Costco in the 2 large loaf packs and freeze one. I use it within about two weeks. Sometimes they have sit for 4 months and been totally fine.
My mom froze cheese one time (grated Mozzerella, and grated Parmesean) and it just didn't work out well. Sometimes you just have to buy fresh. (It was great for pizza though!)
Here is a decent guide to see other things:

HTH!
