One of my plants has quite a few very large tomatoes but they're not
ripening. They're so big their weight has them either sitting, or nearly
sitting on the ground. I'm afraid they're just going to split. Should I
pick them and hope that they get ripe sitting on the kitchen counter?

Buy a package of knee hi nylons, gently sack up the tomato in it while
leaving it on the vine, then stake it up to support it.

I do that with melons growing on a trellis.

Yes, that works quite well. Also good for protecting the fruits from
birds.
