Most BST will use axe/axe at 75, most commonly woods/maneater. Scythe is an option, more rarely used but a bit more attractive since the 2h update.
In terms of BST gear, you'll need a Charm set, TP set and WS set. For Charm set, you'd want a mixture of +CHR (increases charm success rate) and +Charm (increases charm duration - AF has lots of it). For TP set, I'd go with +Haste and +Acc, then for WS build +Acc, then +Atk, +STR in that order, pretty much. Very similar to a lot of other DD.
Once you have that gear sorted out, if you like you can think about Reward and Tame sets, but best to get the basics first.
The islands in Sky are a good place to learn BST if you're going /NIN. Just try Flamingo vs Flamingo, they don't aggro or link, and nothing else aggros except to magic. Take a RR gorget just in case you make a mistake. After a couple of hours you should get the hang of it. Remember to only WS when you know it will kill the mob, otherwise you'll end up tanking.
I could write a ton more but that's a start, hope you have fun.
