There are a couple of good guides on the web, but these are the best instructions and should work well for your situation:

Tomatoes may be frozen whole, sliced, chopped, or puréed. Additionally, you can freeze them raw or cooked, as juice or sauce, or prepared in the recipe of your choice. Thawed raw tomatoes may be used in any cooked-tomato recipe. Do not try to substituted them for fresh tomatoes, however, since freezing causes their texture to become mushy. Tomatoes should be seasoned just before serving rather than before freezing; freezing may either strengthen or weaken seasonings such as garlic, onion, and herbs.

Preparation: Select firm, ripe tomatoes for freezing. Sort the tomatoes, discarding any that are spoiled. Wash them in clean water as recommended above. Dry them by blotting with a clean cloth or paper towels.

Freezing whole tomatoes with peels: Prepare tomatoes as described above. Cut away the stem scar. Place the tomatoes on cookie sheets and freeze. Tomatoes do not need to be blanched before freezing. Once frozen, transfer the tomatoes from the cookie sheets into freezer bags or other containers. Seal tightly. To use the frozen tomatoes, remove them from the freezer a few at a time or all at once. To peel, just run a frozen tomato under warm water in the kitchen sink. Its skin will slip off easily.

Freezing peeled tomatoes: If you prefer to freeze peeled tomatoes, you can wash the tomatoes and then dip them in boiling water for about 1 minute or until the skins split. Peel and then freeze as noted above.

Storage time

To extend the time frozen foods maintain good quality, package foods in material intended for freezing and keep the temperature of the freezer at 0 degrees F or below. It is generally recommended frozen vegetables be eaten within about 8 months for best quality.
