Is there a trick to opening a tube of caulk?

Yes! the tool is called a caulk gun. Use the spout cutter for cutting off the tip of the tube; then use the seal punch tool for poking holes in the foil seal.

Why does caulk sometimes escape the back end of the tube instead of the nozzle?

Did you cut the end, but not poke a hole in the seal down the nozzle at the end of the main tube? That seems like the most likely reason for the set of things that happened here. Many caulking guns ...

How to ensure silicone gun products last as long as possible

Something I've found that's not mentioned yet is the effect of air on adhesives. While sealing up the tip as much as possible is certainly sound advice, I've discovered that tubes and tape last MUCH ...

Why does caulk sometimes escape the back end of the tube instead of the nozzle?

Most, if not all, caulk guns are equipped with an "opening rod" for breaking the seal in a tube of caulk, silicone, or whatever product you are using. By leaving that seal intact you have ...

Is there a trick to opening a tube of caulk?

For UK users there is no separate seal as such, it's part of the tube itself. The top of the threaded part that goes into the nozzle is cut off using a craft knife.

Thorough removal of uncured silicone sealant

I think the products sold as silicone removers will work fine, but I think mineral spirits work too. I'd use an abrasive pad like a Scotch-Brite and maybe a toothbrush-sized wire brush.
