YIKES!! Heavens no! You are rich!
If the plants are sprawling all over the place, don't worry. That's what most tomatoes (indeterminent varieties) do, especially at this time of year.
If you are worried that some tomatoes themselves are laying on the ground, where they *are* more susceptible to critters, etc. just put some straw or paper bags under them.
I'm sure others will chimes in, but I'm also pretty sure there is no such thing as "too many tomatoes"!!!
