Cordon toms

We have been gifted some Tom plants in 4" pots from some neighbours as they have done too many and didn't want to see them go to waste. 

I have been told they are a cordon variety but I wasnt told a variety name. The main problem is I have never grown toms before so am not sure what I'm doing. I have potted them on in to some deeper pots as they were getting a bit pot bound and they were drying out quickly in this weather. Also we don't have a greenhouse so we will need to grow them outside. 

So my question is what next, how big a pot should I be aiming for in the end and what do I need to do with the plant for best results. Thanks everyone.
