It's my first time going and won't be spending too much time in phuket or bangkok, maybe a couple nights in each
Looking for some bar recommendations please as probably won't have the time for too much trial and error!
Unless we have a expat on the ground who knows the scene well, it's just pot luck, bars change, for better or worse, so I can't recommend any in either, my advice is just take a wander about bangla, it's mostly open air beer bars, so easy to check out the girls, no need to sit at the first bar a girl drags you to, as for Bkk you being a newbie stick to lower Sukhumvit rd, do nana plaza, and soi cowboy, and maybe a disco, if you want a soapy massage head up to Ratchada road on the Metro to one of the parlours.
