First of all fold river in the first hand...
The hand in question, I think you need to raise bigger pre. If they're peeling for £14 in a straddled pot they're peeling for £18 imo.
I actually like your peel since villain 2 is short and is highly likely to be putting his remaining £158 into the pot of ~£130 with a range that you absolutely crush. If you were deeper than £270 then I think you have to 4bet because letting the fish call behind for £30 when you're fairly deep would be a criminal loss of value. As it is we don't mind the fish flatting behind because you're happily putting in your remaining £228 on almost all flops to almost any action.
Very happy to jam here, most of the time its the FD+overs, he can have a hand like 88/99 too that he just flatted pre. You don't have the

blocker so he can still have the full range of draws. Sure he has a set sometimes but whatever, definitely happy to get this in. You're getting joke:1 pot odds too, no way you can ever fold.
Edit: flop sizing is fine too imo
