Hi, curious: when should the last of your tomates in garden be picked ? Thanks , in advance.

It depends.  
 
If you intend to can your tomatoes, it's imperative to protect your plants from frost because once the plants are impacted by frost it alters the acidity of the fruit, which can make them unsafe to can. They are still fine to freeze or eat fresh. In that case, you might need to pick them before a frost.  
 
Otherwise, if the plant still looks relatively healthy, you can leave the tomatoes until they are ripe.  
 
If you want to pick them sooner due to frost, the plant starting to die back, or because critters are getting into them, you can pick them anytime even if green. Lay unripened tomatoes in a single layer in a box and check them daily, turning them and removing them as they ripen or you discover they are spoiled.  
 
It's not unusual for it to take them until mid-late September for everything to fully ripen.

When I pick green or under ripe tomatoes will rinse them in water with a bit of bleach to remove any bacteria or dirt and place them on newspaper till ripe . Not sure if it is what your supposed to do but works for me.

Thanks, not too concerned about the ripening part, but wondering if the tomato will continue growing in size, if the plant is still green and healthy?

It depends on the tomato.  
 
If it's a determinate type, then no it won't grow anymore.  
 
If it's indeterminate, then yes it *may* continue to grow in the right conditions. It will theoretically grow new fruit right up until freeze-up.
