Try picking them before they get ripe. Just put them some where inside, but not where the sun will hit them. If the sun shines through the glass, it will blister them. I just put mine in a bowl and set them on the bar.

I pick most my tomatoes greenish white. Otherwise something comes over the fence and takes bites out of them.

Tomatoes ripen from the inside out, they need warmth to ripen not light so if you want you can store them in a dark place. To make a few ripen a little faster place them (not touching each other) in a closed container, this traps the ethylene gas which makes them ripen faster.

Are you watering them too much or is it raining a lot? I'm no expert but my understandind is the cause of splitting is too much water, or more accurately - uneven watering.
